TY - JOUR. T1 - Differences in the contributions of sex linkage and androgen regulation to sex-biased gene expression in juvenile and adult sticklebacks. AU - Kitano, Jun. AU - Kakioka, Ryo. AU - Ishikawa, Asano. AU - Toyoda, Atsushi. AU - Kusakabe, Makoto. PY - 2020. Y1 - 2020. N2 - Different evolutionary interests between males and females can lead to the evolution of sexual dimorphism. However, intersex genetic correlations due to the shared genome can constrain the evolution of sexual dimorphism, resulting in intra-locus sexual conflict. One of the mechanisms resolving this conflict is sex linkage, which allows males and females to carry different alleles on sex chromosomes. Another is a regulatory mutation causing sex-biased gene expression, which is often mediated by gonadal steroids in vertebrates. How do these two mechanisms differ in the contributions to the resolution of intra-locus sexual conflict? The magnitude of sexual conflict often varies between the juvenile and adult stages. ...

Mitochondria not only come exclusively from an organisms mother, they are the power generators of the cells, creating a source of chemical energy known as ATP or adenosine triphosphate. The amount of mitochondria in a cell is based upon the metabolic requirements of that particular cell and the numbers present may range from only one up into the thousands. Therefore, the more demanding the cells energy requirements, the more of these so-called cellular power plants are required. While mitochondria are inherited maternally, it is currently unknown as to what exactly causes the destruction of the paternal side.. Paternal mitochondria are not passed on to an organism. They are either prevented from somehow doing so or are simply destroyed before they can be passed on to any offspring. Scientists are currently looking at this phenomenon to try to find both the reason behind this evolutionary enigma and the manner in which it occurs. Recently, Dr. Eli Arama and colleagues from Weizmann Institute ...
It is not clear whether fast and slow phenotypes have effectively equal fitness under fully aquatic conditions, or whether there are situations that would favour the fast Belize phenotype. One limitation to our microcosm experiment was that fish were unable to disperse. The natural habitat of mangrove rivulus and other rivuline killifishes typically consists of a mosaic of small, intermittent pools (Turko and Wright, 2015; Furness et al., 2018; Sutton et al., 2018). A high metabolic rate is often correlated with high boldness and activity (e.g. Killen et al., 2011; Gangloff et al., 2017), and perhaps Belize fish are more likely to leave water and disperse to unoccupied habitats. We have previously found that metabolic rate of K. marmoratus was positively associated with the frequency of emersion behaviour (Turko et al., 2018). Embryo production by Belize fish was the highest of any strain in our laboratory colony, typical of a dispersal phenotype. Furthermore, when embryo production in the ...
Maternal inheritance of mitochondrial DNA has long been regarded as a major paradox in developmental biology. While some confusion may still persist in popular science, research data clearly document that the paternal sperm-borne mitochondria of most mammalian species enter the ooplasm at fertilization and are specifically targeted for degradation by the resident ubiquitin system. Ubiquitin is a p

Mendel learned the inheritance of seed form first. A cross involving just one trait is known as a monohybrid cross. Mendel crossed pure-breeding (also called true-breeding) smooth-seeded plants with an assortment which had constantly produced wrinkled seeds (60 fertilizations on 15 flowers). All seeds that are resulting smooth. The year that is following Mendel planted these seeds and permitted them to self-fertilize. He recovered 7324 seeds: 5474 smooth and 1850 wrinkled. To support record maintaining, generations had been labeled and numbered. The parental generation is denoted while the P1 generation. The offspring associated with P1 generation would be the F1 generation (very first filial). The self-fertilizing F1 generation produced the F2 generation (2nd filial).

Aged 8 and Wanting a Sex Change is an honest and powerful documentary which follows a number of children in the United States who believe they are the wrong gender.
Assumed maximum length from Ref. 822. Feeds on the hydroid, Abietinaria (Ref. 822). Members of the order Nudibranchia are simultaneous hermaphrodites. Mating behavior: Both individuals darts their penis toward each other to induce one to act as a male and the other as the female. The victorious one to penetrate the body wall is the dominant male. Life cycle: Eggs are deposited on a substratum where they develop and hatch into (planktonic) vestigial veliger larval stage and further grow as adults (Ref. 833). ...
To start a mating, place 4 to 5 young adult (or L4) males on a plate with 4 young adult (or L4) hermaphrodites. We will use plates seeded with a very small drop of OP50 bacteria for our crosses. Using only a small central area of the plate helps our worms find each other quickly and mate. The self-cross progeny produced by the hermaphrodite must be distinguished from outcross progeny. Generally, the hermaphrodite is homozygous for a visible marker and the progeny from self-crossing will show the same phenotype as the hermaphrodite, while progeny from a cross with a wild type male (outcross) will be heterozygous for the maternal marker and thus appear wild type if the mutation is recessive. When no other way is available to distinguish selfcross from outcross progeny, only males are scored. It is the outcross progeny of a mating that are of interest; essentially, all male progeny are crossprogeny. For this reason it is critical than the male transfer not be contaminated with any eggs or ...

Multiple gonadotropin-releasing hormone receptors (GnRHRs) are present in vertebrates, but their differential physiological relevances remain to be clarified. In the present study, we identified three GnRH ligands GnRH1 (pjGnRH), GnRH2 (cGnRH-II), and GnRH3 (sGnRH) from the brain, and two GnRH receptors GnRHR1 (GnRHR IIa) and GnRHR2 (GnRHR IIb) from the pituitary of the ricefield eel Monopterus albus. GnRH1 and GnRH3 but not GnRH2 immunoreactive neurons were detected in the pre-optic area, hypothalamus, and pituitary, suggesting that GnRH1 and GnRH3 may exert hypophysiotropic roles in ricefield eels. gnrhr1 mRNA was mainly detected in the pituitary, whereas gnrhr2 mRNA broadly in tissues of both females and males. In the pituitary, GnRHR1 and GnRHR2 immunoreactive cells were differentially distributed, with GnRHR1 immunoreactive cells mainly in peripheral areas of the adenohypophysis whereas GnRHR2 immunoreactive cells in the multicellular layers of adenohypophysis adjacent to the neurohypophysis.

I am studying sex differentiation of germ cells, namely branching point toward sperms or eggs. My main interests are germ cell differentiation and interaction between germ and somatic cells during this process. I chose teleost fish for the study since their germ cells can differentiate into mature sperms or eggs irrespective of genetic sexes unlike mammals and they exhibit extreme diversity in sex determination/differentiation. Medaka is our favorite. Its sex-determining gene has been identified and both genetic and reverse-genetic tools are readily available. I have been conducting diverse lines of research in medaka such as identification of cis-regulatory elements in oocyte-specific genes by generating transgenic medaka and search for sex differentiation mutants by GFP medaka with oocyte-specific promoters. I also use a hermaphrodite fish, Kryptolebias marmoratus, the only known self-fertilizing vertebrate. I analyze development of their ovotestis where small testicular tissue is ...
Fishes exhibit remarkably diverse, and plastic, patterns of sexual development, most striking of which is sequential hermaphroditism, where individuals readily reverse sex in adulthood. How this stunning example of phenotypic plasticity is controlled at a genetic level remains poorly understood. Several genes have been implicated in regulating sex change, yet the degree to which a conserved genetic machinery orchestrates this process has not yet been addressed. Using captive and in-the-field social manipulations to initiate sex change, combined with a comparative qPCR approach, we compared expression patterns of four candidate regulatory genes among three species of wrasses (Labridae)-a large and diverse teleost family where female-to-male sex change is pervasive, socially-cued, and likely ancestral. Expression in brain and gonadal tissues were compared among the iconic tropical bluehead wrasse (Thalassoma bifasciatum) and the temperate spotty (Notolabrus celidotus) and kyusen (Parajulus poecilepterus)
Helena Dalli (born Elena Abela) is a Maltese politician with the Malta Labour Party, and currently the Minister for European Affairs and Equality. Dalli was crowned Miss World Malta in 1979, representing Sliema. In 1985 she co-starred in Final Justice, an action film starring Joe Don Baker. This would be her only film role. She is a visiting lecturer in Economic and Political Sociology, Public Policy, and Sociology of Law at the University of Malta. In 1996 Dalli was elected to the Parliament of Malta. She was reelected three times, making her the third-most elected woman in Maltese political history. She was a Parliamentary Secretary in the Office of Prime Minister from 1996 to 1998. In that role Dalli presented a Domestic Violence Bill. She is currently the Minister for Social Dialogue, Consumer Affairs, and Civil Liberties within the Maltese Government from 2013-2017 and from the Maltese general election, 2017. She has promoted landmark human rights and equal rights bills, including a Civil ...
In the paper, my co-authors and I suggest two potential mechanisms that may have prevented Gyrodactylus from influencing the guppy-Rivulus interaction. First, the coexistence between guppies and Rivulus has been commonly viewed as a balance between predation and competition, with guppies being the better competitors, but large adult Rivulus actively preying upon juvenile guppies. So, although we did find a trend for a decrease in growth of Rivulus in the presence of size-matched guppies, this was not significantly different from the Rivulus-only control. It is possible that under these experimental conditions competition is lessened due to relatively low fish density per mesocosms; however, an alternative possibility is that Rivulus grow larger than guppies and shift their diet towards terrestrial prey that are too large for guppies to eat, releasing them from resource competition. Indeed, at the end of the experiment Rivulus in the mixed-species treatment were almost three times larger than ...
We think we have a good candidate in the form of a small nematode worm, Caenorhabditis briggsae, which has the following properties. It is a self-fertilizing hermaphrodite, and sexual propagation is therefore independent of population size. Males are also found (0.1%), which can fertilize the hermaphrodites, allowing stocks to be constructed by genetic crosses. Each worm lays up to 200 eggs which hatch in buffer in twelve hours, producing larvae 80 microns in length. These larvae grow to a length of 1 mm in three and a half days, and reach sexual maturity. However, there is no increase in cell number, only in cell mass. The number of nuclei becomes constant at a late stage in development, and divisions occur only in the germ line. Although the total number of cells is only about a thousand, the organism is differentiated and has an epidermis, intestine, excretory system, nerve and muscle cells. Reports in the literature describe the approximate number of cells as follows: 200 cells in the gut, ...

If society allowed men and women to be as they are, such an operation would be nonexistent, as it would have no use. It is a sad thing when someone has to suppress very real aspects of their personality, aspects which will eventually swell like a veritable Prometheus rising, as a raging fire which will not be contained. The problem is, if somebody denies key personality components, these components are very undeveloped, feared, etc., causing the individual to either withdraw from society or lash out against it, among other serious consequences. It places the individual in a downward spiral, as all emotions and logic available are necessary to have a satisfying direction (upward spiral) in ones life. They are perpetually disconnected from the self. I think in a world like we might luckily have, say, 20 years from now or actually, possibly much sooner, this individual would never have even considered such a thing ...
Personally, I dont care how many inmates need sex change operations or new sets of teeth. If a medical professional says they need it, then they should get it. We saw in Sicko that even detainees in Gitmo have all their medical and dental needs taken care of (no word on possible sex change requests in that facility), so why not your average American citizen? If 45 million people in this country do not have health care and many more find their claims denied or up to their ears in medical bills and eventual bankruptcy, then it is pretty darn clear that our medical system is indeed sick and in need of some radical medicine ...
