It has been challenging to genetically improve reproduction traits with the resources of the conventional breeding because of the low heritability of these traits. In Finland genetic improvement of the reproduction traits hasnt either meet the expectations entirely. Gene markers are one possibility to make genetic improvement of the reproduction traits more effective. With an association analysis it is possible to find those gene markers which have statistically significant effect on the trait. The purpose of this study was to identify SNP markers associated with reproduction traits in the Finnish Yorkshire pig breed. Other purpose of this study was to find out if both Finnish pig breeds have certain chromosomal regions associated with same reproduction traits. In this study one goal was also to discover genes which are placed near statistically significant SNP markers. Under this study were nine female reproduction traits which are total number of piglets born in first and later parities, ...

Costs of reproduction are the trade-offs that exist between reproductive investment and survival and/or future reproduction [1,2]. In recent years, studies have focused on the ecological and physiological basis of these costs [3,4]. Such costs include increased oxidative stress (e.g. [5]) and metabolism (e.g. [6]), impaired immune function, and decreased growth, energy stores (e.g. [7]) and endurance (e.g. [8]). Reproductive effort can also have intergenerational effects: offspring quality may decrease when reproductive investment increases, owing to a trade-off between offspring number and quality [2]. Experiments have shown the existence of such a trade-off in mammals, reptiles and birds. For example, offspring from enlarged litters [9,10] or miniaturized eggs [11] have been shown to have a lower survival [10,11], be more stressed and have a lower immune performance [9]. Therefore, parental reproductive effort is linked to offspring quality. Moreover, small offspring can show a period of ...
Fitness trade-offs such as costs of reproduction are an integral component of evolutionary theory, and a common trade-off is that increased reproduction decreases longevity. Our labs interest in reproductive costs stems from its potential to reveal conserved mechanisms that regulate the aging process. When we were in the planning stage of this study, our goal was to explain a recent phenotype we observed where the lifespan of fruit flies was decreased by exposure to pheromones of the opposite sex, and mating actually partially reversed this negative effect. While we were obviously interested in the molecular mechanisms of these phenotypes, we also sought to better understand why this might occur from a conceptual level. Our first thought from this perspective was that the negative effects of pheromones in the absence of mating may be due to a mismatch between expectation and reality. In this line of thought, mating partially rescued the negative effects of pheromones on longevity because the ...

Our second expectation was that the decline in the population growth rate, as observed in wild ungulates, would be caused first by a reduction in foal survival and in reproductive performance and last by the survival of adult females. Foal survival did indeed decline strongly as density increased from 5 to 23 horses km−2. Fecundity was strongly age-structured in these horses, as in wild ungulates, and the fecundity of young females declined at high density (see Duncan 1992), though not significantly in the years up to 1981. The fecundity of young mares in Przewalskis horses (Equus przewalskii) was also density dependent, with a delayed age at first reproduction (Tatin et al. 2009). By contrast with wild herbivores, fecundity in prime-aged Camargue females remained high and quasi-constant at high density. Fecundity is an important criterion for horse breeders in the Camargue (P. Duncan 1979, personal observation), and it is possible that mares of this breed have been selected based on this ...

In humans, early embryo development is a complex process that consists of sequential events: oocyte maturation, fertilization, embryonic growth and implantation. Disruption of these highly regulated processes results in reproductive failure and infertility. This study characterizes and describes embryonic aneuploidy, mitochondrial content level and endometrial microbial environment related to reproductive competence, in particular instances in which failure results. To examine the molecular underpinnings of mammalian gamete and early embryo chromosome segregation, we established a comprehensive chromosomal screening (CCS) method for mice poly bodies, oocytes and embryos by the application of whole genome amplification (WGA) and next generation sequencing (NGS). First, we validated this approach using single mouse embryonic fibroblasts engineered to have stable trisomy 16. We further validated this method by identifying reciprocal chromosome segregation errors in the products of meiosis I (gamete and

The bromophenol 2,4,6-tribromophenol (TBP) is widely used as an industrial chemical, formed by degradation of tetrabromobisphenol-A, and it occurs naturally in marine organisms. Concentrations of TBP in fish have been related to intake via feed, but little is known about effects on fish health after oral exposure. In this study, we exposed adult male and female zebrafish (Danio rerio) to TBP via feed in nominal concentrations of 33, 330, and 3300 μg/g feed (or control feed) for 6 weeks to assess the effects of TBP on reproductive output, gonad morphology, circulatory vitellogenin levels, and early embryo development. The aim was also to investigate the extent to which TBP was metabolised to 2,4,6-tribromoanisole (TBA) in dietary exposed zebrafish, and the amounts of TBP and TBA found in offspring. After 6 weeks of exposure, we found about 3% of the daily dose of TBP in adult fish and the mean concentration of TBA was 25-30% of the TBP concentration. TBP and TBA were detected in offspring with ...

Prenatal and preimplantation testing technologies have offered unprecedented access to information about the genetic and congenital makeup of our prospective progeny. Future developments such as preconception testing, noninvasive prenatal testing, and more extensive preimplantation testing promise to increase that access further still. The result may be greater reproductive choice, but it also increases the burden on women and men to avail themselves of these technologies in order to avoid having a child who has a disability. The overwhelming question for legislators has been whether and, if so, how to regulate the use of these technologies in the face of compelling but seemingly contradictory claims about the advancement of reproductive choice and the dangers of eugenic or discriminatory effects. This book examines the evolution of this legislative oversight across a number of jurisdictions and explores the tensions and ambiguities that inform these laws. ...

Summary - The reproduction of Radopholus similis isolates from different origins and hosts was compared in carrot disk cultures at different temperatures. At 15°C, only the isolates collected from ornamental plants in Europe reproduced. The greatest fecundity was observed at 25°C. The reproduction factor (final population/initial population: Pf/Pi) ranked the isolates in similar order for four of the temperatures studied (15, 20, 25 and 30°C). When carrot discs at 28°C were inoculated with single females of isolates selected from those with different reproductive factors, this ranking was confirmed. This suggests that reproduction is controlled by intrinsic isolate characteristics which are not influenced by temperature. Isolates with most reproduction had a greater percentage of reproductive females than isolates with less reproduction, associated with a high ratio of females : males and a high proportion of females in the total production. The mean offspring per productive female was similar for
reproductive system - Reproductive Cells and Gonads - The basic organs of sexual reproduction are the gonads, which are ovaries in females and testes in males. The gonads are dormant until they are activated by hormones at sexual maturity. (See also Sexuality.)The male gametes, called spermatozoa or sperm, are produced in the testes. Spermatozoa are microscopic tadpole-shaped cells with long tails. In all invertebrates the testes are internal, but in most mammals, including humans, they lie in an external sac called the…
This one-generation study assessed the potential of esterified propoxylated glycerol (EPG) to affect reproduction and offspring development in rats. Male and female Crl:CD(SD)BR rats (30/sex/group) were exposed to EPG at 0, 0.5, 1, and 2g/kgbw/day or at 5% (w/w) in the diet prior to (13weeks), during, and after two consecutive matings. For dams, exposure continued through gestation and lactation; F1a and F1b pups were weaned to the respective diet (for up to 91days).
The peculiar bone histology of Myotragus provides direct evidence of the developmental and growth strategy and indirect evidence regarding the physiology of this insular dwarf mammal. The presence of lamellar-zonal bone throughout the cortex indicates that Myotragus grew at slow and variable rates and ceased growth cyclically, which was associated with an important delay in the attainment of skeletal (sexual) maturity. Consistent with life history theory (30), the extended juvenile development of Myotragus was associated with an extended life span as indicated by the elevated number of very old individuals in the fossil assemblages (10). Our empirical finding, hence, does not support the prediction that life history traits of insular dwarfs accelerate to increase reproductive investment (12-15), but instead lends support to the model that predicts a shift in life history traits toward the slow end of the slow-fast continuum with a delay in age at maturity and an extended life span (16).. True ...
Our data provide no evidence that positive selection is enhanced in sympatry, and if these candidate GRPs are involved in prezygotic isolation, we have no evidence for enhanced prezygotic isolation. The polymorphism statistics likewise give no indication that RCD is occurring in these three proteins.. We cannot necessarily conclude from lack of evidence for RCD in CIPRO37.40.1, CIPRO60.5.1 and CIPRO100.7.1 that RCD is not occurring in this system. If enhanced prezygotic isolation between Type A and B does exist, there are several reasons why we might not have detected it in this study. First, primers for candidate GRPs were developed from the Type A genomic sequence and were used to amplify and sequence both Type A and B individuals (the Type B genome has not been sequenced). But Type A and B are substantially divergent (p-distances: 0.124 at mtCOI, 0.035 to 0.116 for six nuclear loci; [43]), which could explain why 15 genes encoding GRP candidates could not be successfully amplified and/or ...
... is the process responsible for the creation of a zygote. A zygote is a diploid cell (2n) which is created by the fusion of two haploid germ cells (n), the female and male gametes.. The zygote is representative of an organisms earliest stage of development. Once fertilization takes place between the female ovum and the male sperm cell, a single diploid cell is formed. The DNA of both parents contributes to this diploid cell. The specifics of reproduction in different eukaryotic organisms vary and in plants reproduction is often asexual. Asexual reproduction produces identical copies of the parents except when mutations take place.. In eukaryotes, there are two main processes in sexual reproduction. First there is meiosis and then fertilization. During fertilization the two gametes are fused together, which regenerates the number of chromosomes of the newly formed cell back to normal (46 chromosomes), since during meiosis the number of chromosomes is halved.. Sexual ...

University of Chicago researchers have made a discovery which is claimed to give major support to Darwins theory that the most important urge in organisms is the drive to mate.. Nature magazine reports that the study compared three sets of genes linked to male reproduction in humans, chimpanzees, gorillas and orangutans. Humans and chimps are closely related, and it would have been expected that their genes would not be much different even after millions of years of evolutionary divergence.. But the study found these particular genes were very different between the two species. This difference indicated that the genes were evolving very rapidly.. "The pressure on a male to find a mate and fertilize her eggs is constant, and the stakes of success or failure are enormous," said co-author Professor Chung-I Wu. "Presumably, genes governing male reproduction are under continuous pressure to evolve ways to outcompete other males when it comes to fathering offspring.". Wu said his work concurred with ...

All else being equal, an asexually reproducing population will grow at twice the rate as a sexually reproducing population. The reason for this is simple: members of a sexually reproducing population must produce both sexes, but effectively only half of them can give birth to offspring ot their own. In contrast, all offspring of an individual from an asexually reproducing population can potentially give birth. This is the two-fold cost of sexual reproduction.. Despite this cost, sexual reproduction is a prevalent mode of reproduction. Therefore, there must be some advantage to reproducing sexually, or else the sexually reproducing populations would soon become replaced by the much larger sexual populations. One advantage of sexual reproduction is that sexual reproduciton maintains more genetic variation than asexual reproduciton. ...

Modern highly prolific females have more defined nutrient requirements than females 20 yr ago [30], thus continuous updating of nutrient requirements and management techniques and technologies are required [10, 23, 30-36]. The effect of environmental factors, such as temperature, humidity and building design on feed intake during lactation should be considered.. Gestation: It is well documented that "flushing" by increasing feed by 50-100% or feeding sources of high energy, such as dextrose for 10-14 d before first service, increases ovulation rate and litter size. However, there are conflicting reports in the literature regarding feeding programs during the remainder of gestation [37]. Vignola [38] reviewed research indicating that feed intake should then be decreased after mating to an appropriate gestation diet because sows that are overfed throughout gestation, especially during the first two weeks after breeding, frequently have high embryonic mortality and produce small litters. Sows, ...

Yeast produce a majority of their esters right at the point where they get the signal they are running out of a some required nutrient. The yeast metabolism shifts from growth to maintenance fermentation and some storage carbo accumulation. The half-built fatty (short chain) acids the yeast were constructing for growth/reproduction are not only unnecessary but toxic. Perhaps for this reason the yeast produce a burst of enzymes just as growth ceases which, together with some energy and the abundant alcohols convert the fatty acids to esters, The esters are ...

Reproductive characteristics of the bathyal viviparous fish Cataetyx alleni (Osteichthyes: Bythitidae) from the southeastern Sardinian Sea (central-western Mediterranean) MARIA
A central point of Barnard College President Debora Spars 2006 book The Baby Business is the widespread American reluctance to acknowledge that assisted reproduction is a commercial enterprise that is subject to the full force of market dynamics.8 It is now a $3 billion dollar a year industry in the United States,8 with tens of thousands of patients/consumers each year. But unlike other developed countries such as Canada and the UK, the United States has allowed the business of assisted reproduction to develop in a largely unregulated manner. We have neither a public health care system nor many private insurance companies that provide coverage for assisted reproduction, and we have little public oversight of the fertility industrys practices.. By contrast, many other industrialized countries have adopted public policies to protect fertility patients, their children and third parties involved in assisted reproduction, and also to prevent socially unacceptable practices. The UK is the best ...
Animals which reproduce sexually have a better advantage Photo: Jebulon. Researchers at the University of Edinburgh studied sexual reproduction in tiny fruit flies to learn more about how DNA is randomly shuffled when the genes of two parents combine to create a new individual.. They found that this recombination of genetic material allows for damaging elements of DNA - which might cause disease or other potential drawbacks - to be weeded out within a few generations. Individuals who inherit healthy genes tend to flourish and pass on their DNA to the next generation, while weaker individuals are more likely to die without reproducing.. The findings, made possible by genome sequencing technology, provide strong evidence to back up a long-standing theory that sexual reproduction, rather than asexual cloning of an individual, has long-term benefits for a species.. Scientists studied how the DNA of fruit flies is affected when the recombination of DNA does not occur. They found that harmful DNA ...

The results of the model highlight the fact that the evolution of a more-grouped life cycle (increasing p) affects fitness components that are already being affected by previously optimized life-history traits, such as growing time tgr. Life-history traits are closely related to fitness and subject to a constraining trade-off. A fundamental trade-off faced by all organisms is between reproduction and survival. As p increases, all else equal, fecundity decreases and viability increases (because of α and β). Even if the net effect of this change in p is positive, the contrasting effect of changing p on fitness components that trade off with life-history traits such as tgr can be sub-optimal. When p changes, a cell does better (existing as it does for some time in a group context) if it can also adjust tgr to bring the fitness components back into balance. In addition to its direct effects on fitness, increasing tgr increases fecundity and decreases viability, essentially counteracting the lack ...

Why do race stereotypes take the forms they do? Life history theory posits that features of the ecology shape individuals behavior. Harsh and unpredictable ("desperate") ecologies induce fast strategy behaviors such as impulsivity, whereas resource-sufficient and predictable ("hopeful") ecologies induce slow strategy behaviors such as future focus. We suggest that individuals possess a lay understanding of ecologys influence on behavior, resulting in ecology-driven stereotypes. Importantly, because race is confounded with ecology in the United States, we propose that Americans stereotypes about racial groups actually reflect stereotypes about these groups presumed home ecologies. Study 1 demonstrates that individuals hold ecology stereotypes, stereotyping people from desperate ecologies as possessing faster life history strategies than people from hopeful ecologies. Studies 2-4 rule out alternative explanations for those findings. Study 5, which independently manipulates race and ecology ...

Those governing differences are the genetic differences in a group of organisms in the environment you are considering ...

Apparatus for stopping the reproduction of the video information from a record medium (e.g., the video CD recorded by the MPEG1 method) is provided. A group index detector detects a group index identifying the picture group including the picture being displayed when an external reproduction stop signal is inputted. A group index memory stores this detected group index. A record position detector detects the record position (e.g., a stop sector address) of the picture being processed when the external reproduction stop signal is inputted as well as output record position information representing the detected record position. A record position memory stores this detected record position information.
A reproduction apparatus is designed to select and decode speech and subtitles (characters) in a given language from a disk on which various types of information are recorded in different languages. This system arrangement makes it possible to standardize the manufacture of disks and reproduction apparatuses world-wide, resulting in a reduction in production cost. In a disk 100, various types of information are recorded in different languages along with video information. A reproduction apparatus selects information in a given language from the reproduced information using a data string processing section 203, a system control section 204, and an operator section 205, and supplies the selected pieces of information to each of a video processing section 206, a subtitle decoder 211, and an audio processing section 213.
The medical reproduction system is a computer-based interactive reproduction system device designed to be used by physicians and technicians in medical training and diagnosis using medical systems such as ultrasound machines. Biological data is collected from a living body and stored in memory. An operator manipulates a simulated sensor over a transmitter which may be attached to a simulated body. The transmitter transmits position data to a receiver in the sensor. The reproduction unit processes the preset biological data and displays data corresponding to the position of the sensor with respect to the transmitter.
In mammals, maternal investment is a key determinant of reproductive fitness, as young are unable to survive without milk and adequate maternal care (Walser, 1978; Clutton-Brock, 1991). This is particularly true in gregarious species in which reproduction is highly synchronised and many young are born within a limited time of the year; if the mother provides milk to non-kin young she may reduce her investment in her own offspring (González-Mariscal and Poindron, 2002; Poindron et al., 2007). In such situations, mother-young recognition at the time of suckling is critical to maximise maternal investment. Sheep constitute a good example of mammals living in large groups with synchronised seasonal breeding, in which mutual mother-young recognition ensures exclusive care of their own progeny (Lynch et al., 1992; Poindron et al., 2007).. In this species, olfaction has long been recognized as the critical sensory modality controlling exclusive acceptance of the mothers own lamb at nursing (Bouissou, ...

EDITORS NOTE: Evolutionary theory continues to be plagued by persistent problems that defy solution via rational thought. This is true whether one examines the origin of the Universe-or the origin of life. But nowhere is the glaring inadequacy of evolutionary theory more evident than in its feeble and failed attempts to explain the origin of sex. The pervasive presence of the male and female sexes (whether in plants, animals, or humans), and the ubiquitous nature of sexual reproduction based on differences in gender, deftly defy any naturalistic explanation. This two-part series of articles will examine topics of a potentially sensitive nature (due to the subject matter under review). However, Dr. Harrub and I want to assure each of our readers that we have absolutely no intention of stooping to "street slang" to do so. Appropriate medical terminology will be employed, and the discussion of the issues involved will be carried out in a straightforward, scientific, and respectful manner. We ...

Bill Nye talks about the realities of reproduction, and the right wing completely loses its shit. It is not Nye at his most eloquent, but…hes actually right about everything important. Read this title for an example of the inanity of far right responses, titled WATCH: Bill Nye, Science Guy Makes An Idiot Of Himself On Reproduction. Nye is clearer and more correct than whoever wrote that, making it particularly amusing. It makes a lot of claims. Not that this writer had all that great an affinity for Bill Nye anyway, but the video below has to be the most smug, snide, atheistic diatribe… ...
Researchers have found that lowering the levels neuropeptide natalisn can lower the reproductive ability of insects. The main implication of the study is that controlling natalisn can help curb the population of insects. It could pave way for a new, efficient and environmentally safe pest management system.
A new medical test for women who want to check their biological clocks is debuting in Chicago amid concerns about its usefulness and enormous interest in the consequences of delayed childbearing.. Called Plan Ahead, it is the first fertility test that purports to measure a womans ovarian reserve -- how many good eggs she has available for conception.In a controversial move, the $350 test will be marketed to women who are contemplating when to have children and who want to recognize any potential biological limitations.. Dr. Benjamin Leader, chief medical officer for the company marketing the test, Repromedix, compares it to checking the gas gauge on a car to see how much is left in the tank.. But some fertility experts worry that the sales pitch will capitalize on womens anxieties and note that the tests reliability has not been clearly established.. Given the state of the science, I think its premature to offer this test, said Dr. Ralph Kazer, chief of reproductive endocrinology and ...
Ive said it before, but maybe if a guy who specializes in contraceptive research at the one of the countrys foremost reproductive health institutes says it, people will finally understand.

Today was the Egg Retrieval day! We have great EGGSpectations for today! Ha Ha! We drove through the bad bad fog to Rochester and checked into the hospital at 7:30am. We waited together in the room for about an hour, then I was wheeled down to wait in pre-op for another 40 minutes by myself watching all the "sick" people getting wheeled into their surgeries. It made me actually thankful for the reason I was there. I looked absolutely stunning in my hospital gown, sockies, and cap. Ha Ha! The head of the "Reproductive Endocrinology and Infertility Department" came and spoke with me. I was relieved to know he was doing the egg retrieval! He is such an amazing man. The moment he looks at you and starts speaking, you just feel the love. He makes you feel cared for and peaceful. Everyone who helped me today was so friendly and nice, which helped me stay calm ...

Dr. Shirk has worked extensively on female reproduction and germ cell development in insects and conducted pioneering work on gene vector systems for germline and somatic transformation of insects. This work on somatic transformation allows the phenotyic expression of candidate genes to be examined prior to the laborious task of creating germ-line modified strains. As these studies mature they will be a valuable compliment to the research of Drs. Handler and Nagoshi into transposable elements and the creation of conditional-lethality ...
Helpful, trusted answers from doctors: Dr. Opsahl on a man on dyalisi can he have children: The reproductive capability of the testis is so strong that a well controlled dialysis patient is likely still fertile. Conditions or treatments leading to the dialysis may have reduced fertility some, but a few simple tests at a fertility center could verify the sperm production and expected quality.
GnRH is needed for sexual maturity and normal reproduction. GnRH acts by stimulating the release of luteneizing hormone and follicle-stimulating hormone from the anterior pituitary. These two gonadotropins act by stimulating the production of sex hormones in the gonads (testes and ovary ...
