Sex ratio. Medical search

The number of males per 100 females.

Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from SEX CHARACTERISTICS, anatomical or physiological manifestations of sex, and from SEX DISTRIBUTION, the number of males and females in given circumstances.

The mechanisms by which the SEX of an individual's GONADS are fixed.

Those characteristics that distinguish one SEX from the other. The primary sex characteristics are the OVARIES and TESTES and their related hormones. Secondary sex characteristics are those which are masculine or feminine but not directly related to reproduction.

Validation of the SEX of an individual by inspection of the GONADS and/or by genetic tests.

Evaluation of life-cycle herd efficiency in cow-calf systems of beef production. (1/1154)

A deterministic beef efficiency model (BEM) was used to evaluate life-cycle herd efficiency (LCHE) in cow-calf beef production systems using four breed groups of beef cattle. The breed groups were Beef Synthetic #1 (SY1), Beef Synthetic #2 (SY2), Dairy Synthetic (DS), and purebred Hereford (HE). The LCHE was defined over the lifetime of the herd as the ratio of total output (lean meat equivalent) to total input (feed equivalent). Breed differences in LCHE were predicted with the larger/slower maturing DS being most efficient at each age of herd disposal and reproductive rate. This was mainly because, at any average age at culling, the dams of DS breed group were less mature and so had been carrying relatively lower maintenance loads for shorter periods and positively influencing LCHE. Higher LCHE was predicted with improvement in reproductive performance if there were no associated extra costs. However, this declined markedly if there was a delay in marketing of offspring. As average age at culling increased from 4 to 6 yr, efficiency declined sharply, but it began to recover beyond this age in most breed groups. We concluded that the slower maturing DS breed group may be more efficient on a herd basis in cow-calf systems and that improvements in reproductive rate not associated with extra costs improve life-cycle efficiency. Culling cows soon after their replacements are produced seems efficient. (+info)

Placenta previa: preponderance of male sex at birth. (2/1154)

To determine the relation between placenta previa and male sex at birth, the authors conducted two types of analysis: 1) a historical cohort analysis of singleton live births in New Jersey hospitals during 1989-1992 (N = 447,963); and 2) a meta-analysis of previously published studies on the subject. For the cohort analysis, subject mother-infant dyads were identified from linked birth certificate and maternal and infant hospital claims data. The infant's sex for mothers with an International Classification of Diseases, Ninth Revision, Clinical Modification, code of 641.0-641.1 for placenta previa (n = 2,685) was compared with infant's sex for mothers without placenta previa (n = 445,270). For the meta-analysis, seven published articles were located and summary effects were calculated using both fixed-effect and random-effects models. In the present cohort study, the male:female ratio at birth was significantly higher in women with placenta previa (1.19) than in those without placenta previa (1.05) (p<0.001). The association of placenta previa with male sex persisted when the analysis was either stratified or adjusted for the effects of maternal age, maternal parity, maternal smoking during the index pregnancy, race/ethnicity, the infant's gestational age, and the infant's birth weight. The meta-analytic results from the fixed-effect and random-effects models showed a 14% excess of placenta previa when women were carrying a viable male fetus as compared with a viable female fetus during pregnancy. The results were the same regardless of whether the present cohort study was included in the meta-analysis. In conclusion, the evidence obtained from these analyses strongly argues for an association between placenta previa and male sex at birth. The mechanism for this association remains to be determined.

Spiroplasma poulsonii sp. nov., a new species associated with male-lethality in Drosophila willistoni, a neotropical species of fruit fly. (3/1154)

Progenies from some wild-caught females of Drosophila willistoni and three other sibling species are entirely female. The proclivity for production of unisexual female progeny by these flies was named the sex ratio (SR) trait and was originally thought to be genetic. However, experiments in the laboratory of Donald F. Poulson in the early 1960s demonstrated that this 'trait' was vertically transmitted and infectious, in that it could be artificially transferred by injection from infected females to non-infected females. Motile, helical micro-organisms were observed in females showing the trait. In 1979, the SR organisms were designated as group II in the informal spiroplasma classification system. The organisms proved to be extremely fastidious, but were eventually cultivated in a very complex cell-free medium (H-2) after initial co-cultivation with insect cells. Cultivation in the H-2 medium and the subsequent availability of a triply cloned strain (DW-1T) permitted comparative studies. Cells of strain DW-1T were helical, motile filaments 200-250 nm in diameter and were bound by a single trilaminar membrane. Cells plated on 1.8% Noble agar formed small satellite-free colonies 60-70 microns in diameter with dense centres and uneven edges. The temperature range for growth was 26-30 degrees C; optimum growth occurred at 30 degrees C, with a doubling time in H-2 medium of 15.8 h. The strain passed through filters with 220 nm, but not 100 nm, pores. Reciprocal serological comparisons of strain DW-1T with representatives of other spiroplasma groups showed an extensive pattern of one-way crossing when strain DW-1T was used as antigen. However, variable, usually low-level reciprocal cross-reactions were observed between strain DW-1T and representatives of group I sub-groups. The genome size of strain DW-1T was 2040 kbp, as determined by PFGE. The G + C content was 26 +/- 1 mol%, as determined by buoyant density and melting point methods. The serological and molecular data indicate that strain DW-1T is separated from group I representative strains sufficiently to justify retention of its group status. Continued group designation is also indicated by the ability of SR spiroplasmas to induce male lethality in Drosophila, their vertical transmissibility and their extremely fastidious growth requirements. Group II spiroplasmas, represented by strain DW-1T (ATCC 43153T), are designated Spiroplasma poulsonii. (+info)

Estimating population size by genotyping faeces. (4/1154)

Population size is a fundamental biological parameter that is difficult to estimate. By genotyping coyote (Canis latrans) faeces systematically collected in the Santa Monica Mountains near Los Angeles, California, we exemplify a general, non-invasive method to census large mammals. Four steps are involved in the estimation. First, presumed coyote faeces are collected along paths or roadways where coyotes, like most carnivores, often defaecate and mark territorial boundaries. Second, DNA is extracted from the faeces and species identity and sex is determined by mitochondrial DNA and Y-chromosome typing. Third, hypervariable microsatellite loci are typed from the faeces. Lastly, rarefaction analysis is used to estimate population size from faecal genotypes. This method readily provides a point count estimate of population size and sex ratio. Additionally, we show that home range use paternity and kinship can be inferred from the distribution and relatedness patterns of faecal genotypes. (+info)

Factors affecting the number of teats in pigs. (5/1154)

The factors that affect the number of teats in pigs are of interest for both biological and practical reasons. Previous work indicates that there is a genetic component, principally from the dam. The proportion of males in a litter appears to be related to the anogenital distance of the gilts in the litter, possibly as a result of the intrauterine position effect. The present study investigated whether litter size, litter sex ratio, anogenital distance, crown-rump length, distance from base of skull to base of tail, and the number of teats on the dam and boar affected the number of teats on gilts. Stepwise multiple regression on litter mean values (adjusted r2 = 0.178) indicated that two factors were significant: the number of teats on the dam (standard coefficient 0.311) and the proportion of males in the litter (standard coefficient -0.282). A greater number of teats on the dam and a lower proportion of males in the litter resulted in a greater number of teats on the gilt. When the analysis was run using individual gilts as the independent units (adjusted r2 = 0.073), the number of teats on the dam (standard coefficient 0.207), the proportion of males in the litter (standard coefficient -0.135), and the weaning weight of the gilt (standard coefficient 0.083) were all significant predictors of the number of teats. This evidence suggests that teat number in female pigs is related to the proportion of males in the litter. (+info)

Allosomal and autosomal control of sex ratio in PHH and PHL mice. (6/1154)

When male mice from inbred PHH (sex ratio .535) and PHL (.435) are mated to females of various inbred lines, the sex ratio follows the male parent. The sex ratios from litters sired by reciprocal cross F1 males (letting A represent a set of autosomes) are 0.510 from AH/AL, XL/YH and 0.469 from AH/AL, XH/YL. The difference is statistically significant but only half the difference between pure strains. The paternal effect, presumably due to the Y, persists in progeny of the two kinds of F2 males. In backcrosses to the female parent, resulting finally in AH/AH, XH/YL and AL/AL, XL/YH, and in outcrosses, the effect of the Y chromosome does not persist, indicating that neither the Y alone, nor the autosomes alone, will cause the sex ratio to depart significantly from equality of sexes. When pairs of males in all possible combinations were presented with C57BL/6 females mating success gave the following ranking: AH-YL, AL-YL, AH-YH, AL-YH. The combination of autosomes from PHH and Y-chromosome from PHL seems to confer the greatest competitive advantage. (+info)

Muscle growth and development in normal-sex-ratio and all-female diploid and triploid Atlantic salmon. (7/1154)

Muscle development and growth were investigated in diploid populations of normal-sex-ratio and all-female Atlantic salmon (Salmo salar L.) and their triploid counterparts produced by high-pressure treatment. Somites were formed at the rate of 6 h-1 in both diploids and triploids at 6 degrees C. The rostral-to-caudal development of myotubes, myofibrils and acetylcholinesterase staining at the myosepta was slightly more advanced in triploid than in diploid fish, although the differences were smaller than among individual families. The c-met receptor tyrosine kinase was used as a molecular marker for the satellite cells involved in postembryonic muscle growth. Satellite cell nuclei comprised 17.5 % of total myonuclei in smolts and they were 24 % more abundant in diploid than in triploid fish. Cells expressing the myogenic regulatory factor myf-6, a marker of satellite cells committed to differentiation, represented 14.8 % of total myonuclei in diploids and 12.5 % in triploids. At ambient temperatures, the number of white muscle fibres in normal-sex-ratio fish increased more than 30-fold between the alevin and smolt stages, and approximately 3.5-fold further during the first year of seawater growth. The rate of muscle fibre recruitment in seawater stages was significantly greater in diploid than in triploid fish, reaching 1162 fibres day-1 and 608 fibres day-1, respectively, in all-female groups 800 days post-hatching. For 42 cm fork-length fish, there were approximately one-third more muscle fibres per myotome in diploid than in triploid groups, 649 878 and 413 619, respectively, for all-female fish. The probability density function of muscle fibre diameters in each fish was estimated using non-parametric smoothing techniques, and the mean densities for diploids (fD) and triploids (fT) were calculated. The peak fibre diameter was approximately 20 (micro)m in all age classes, irrespective of ploidy. Distinct bimodal distributions of muscle fibre diameter were evident in all groups 775 days and 839 days post-hatching, reflecting seasonal cycles of fibre recruitment. fD and fT were compared using a non-parametric bootstrap technique and the reference band representing the null-hypothesis indicated that there was no difference with ploidy. Reference bands for normal-sex-ratio fish at 315 days and 470 days indicated that diploids had a higher percentage of smaller-diameter fibres and that triploid distributions had a thicker right-hand tail. Similar differences in fD and fT of muscle fibre diameters were found for all-female fish, although the statistical evidence was less strong. Reference bands indicated differences in the middle range of the distributions of muscle fibre diameter in fish 620-775 days post-hatch, with triploids having a thicker right-hand tail. Thus, a lower density of satellite cells was associated with reduced rates of fibre recruitment but a compensatory increase in muscle fibre hypertrophy in triploid compared with diploid fish.

In the medical field, "crows" typically refers to a type of facial aging that results in the formation of deep wrinkles and creases around the eyes, nose, and mouth. These wrinkles are often referred to as "crow's feet" or "laugh lines" and are caused by a combination of factors, including genetics, sun exposure, and the natural aging process. In some cases, crows feet may be treated with cosmetic procedures such as dermal fillers, botox, or laser therapy. However, it is important to note that these treatments may not be suitable for everyone and should only be performed by a qualified medical professional. Additionally, preventative measures such as wearing sunscreen and avoiding excessive sun exposure can help reduce the formation of crows feet over time.

In the medical field, competitive behavior refers to the actions or behaviors that healthcare providers engage in to attract and retain patients, gain market share, and increase revenue. This can include offering discounts or promotions, advertising services or specialties, or competing on the basis of price or quality. Competitive behavior can also refer to the actions or behaviors that healthcare providers engage in to compete with other healthcare providers for resources, such as funding, equipment, or personnel. This can include lobbying for government funding or advocating for policies that benefit their organization. While competitive behavior can be beneficial in promoting innovation and improving the quality of care, it can also lead to negative consequences, such as over-treatment, medical errors, and a focus on profit over patient well-being. As such, healthcare providers must balance the need to compete with the ethical and moral obligations to provide high-quality, patient-centered care.

Disorders of Sex Development (DSD) are a group of conditions that affect an individual's development of their reproductive system. These conditions can cause variations in the anatomy, hormones, and/or chromosomes of an individual, leading to differences in their sex characteristics. DSD can be classified into four categories: 1. Intersex: This category includes individuals who have variations in their sex chromosomes, gonads, or genitalia that do not fit typical male or female characteristics. 2. Androgen Insensitivity Syndrome (AIS): This category includes individuals who have a normal amount of sex chromosomes but are resistant to androgens, which are male hormones. This can result in a range of genital and sexual characteristics that do not fit typical male or female characteristics. 3. Congenital Adrenal Hyperplasia (CAH): This category includes individuals who have a genetic defect that affects the production of hormones in the adrenal glands. This can result in the development of ambiguous genitalia or other sex characteristics that do not fit typical male or female characteristics. 4. Gonadal Dysgenesis: This category includes individuals who have a genetic defect that affects the development of their gonads (ovaries or testes). This can result in the development of ambiguous genitalia or other sex characteristics that do not fit typical male or female characteristics. DSD can have a significant impact on an individual's physical, emotional, and social well-being. Treatment options for DSD may include hormone therapy, surgery, and counseling to help individuals and their families cope with the challenges associated with these conditions.

Biological evolution refers to the process by which species of living organisms change over time through the mechanisms of natural selection, genetic drift, mutation, and gene flow. In the medical field, biological evolution is important because it helps us understand how diseases and pathogens have evolved and adapted to survive in different environments and populations. This knowledge is crucial for developing effective treatments and prevention strategies for infectious diseases, as well as for understanding the genetic basis of inherited diseases and disorders. Additionally, understanding the evolutionary history of organisms can provide insights into their biology, ecology, and behavior, which can inform conservation efforts and the management of natural resources.

In the medical field, birth order refers to the position of a person in their family in terms of their birth order. It is a commonly studied topic in the field of psychology and has been linked to various personality traits, behaviors, and outcomes. The concept of birth order suggests that the birth order of siblings can influence their personality, behavior, and development. For example, first-born children are often seen as more responsible, organized, and ambitious, while middle children may be more adaptable and outgoing, and youngest children may be more creative and independent. Birth order can also be influenced by factors such as family size, gender, and the age gap between siblings. For example, families with larger families may have more opportunities for siblings to interact and develop their own unique personalities, while families with smaller families may have more pressure on each child to excel. Overall, birth order is an important factor to consider in understanding individual differences in personality and behavior, and can provide valuable insights into the development of children and families.

I'm sorry, but I'm not aware of any specific medical term or concept related to the country of Azerbaijan. Azerbaijan is a country located in the South Caucasus region of Eurasia, and it is known for its rich cultural heritage, natural resources, and geopolitical significance. In the medical field, Azerbaijan has a developed healthcare system with a focus on primary care and preventive medicine. The country has made significant progress in improving access to healthcare services and reducing mortality rates in recent years. However, there are still challenges related to the quality and availability of healthcare services, particularly in rural areas.

For species where the cost of successfully raising one offspring is roughly the same regardless of its sex, this translates to an approximately equal sex ratio. (wikipedia.org)
The sex ratio of C5 (female : male) was approximately 1 : 1 throughout the year. (brill.com)

Biological research mostly concerns itself with sex allocation rather than sex ratio, sex allocation denoting the allocation of energy to either sex. (wikipedia.org)

In modern language, the 1:1 ratio is the evolutionarily stable strategy (ESS). (wikipedia.org)
