The sexually dimorphic expression of androgen receptors in the song nucleus hyperstriatalis ventrale pars caudale of the zebra finch develops independently of gonadal steroids. Nevertheless, if the testes are the primary source of a masculinizing hormone, it is fair to differences between autosomes and sex chromosomes in Markham significant masculinization of the brain of the testes-bearing females, which was not observed.
Aggressive behaviors in adult SF-1 knockout mice that are not exposed to gonadal steroids during development. Recent findings, however, suggest that brain cells that differ in their genetic sex are not equivalent, and that difference may contribute to sex differences in brain function.
An obvious, and important, question which arises from this finding, is whether the effect is generalisable to a non-clinical male differences between autosomes and sex chromosomes in Markham - if it is, identifying and characterising the causal variant will be a priority.
In addition to its relevance to sex differences, the comparison of XO vs. However, as Sts is non-pseudoautosomal in rats and has no detectable Y homologue [ 91 ], these neurobiological effects must be attributable to the X-linked Sts gene. This finding suggests that differences between XX and XY mice of the same gonadal type might not be mediated by more minor within-sex differences in the levels of gonadal hormones.
One mouse model of SLE involves the injecting the mouse with pristane, a saturated terpenoid alkane, which causes female-biased pathology of the kidney and other organs, and ultimately death.
Expression of steroid sulfatase during embryogenesis. The present paper reviews evidence from human genetic studies and animal models for Y-linked effects both direct and indirect on neurodevelopment, brain function and behaviour. In this context, we studied chromosomes, which are found in the nucleus and contain the hereditary material.
There are a few numbers of sex chromosomes in our genome.
