Here we investigate the intrinsic sex identity of the brain by constructing chicken chimeras in which the brain primordium is switched between male and female identities before gonadal development. We find that the female chimeras with male brains display delayed sexual maturation and irregular ...
This balance is altered in accordance with the competing demands of the potential cost of infection versus that of increased reproductive success30,31. While it is currently unknown why females prefer higher T males in Japanese quail, the evidence suggests that aggressive male behavior, which is ...

name of the first described retroviral oncogene (v-src), from the chicken Rous sarcoma retrovirus and its precursor (c-src), which encode a membrane-associated protein kinase. SURG-1: sequence underlying responsiveness to GnRH element SVOG-4m: human ovarian granulosa-luteal cell line TLCs: th...
The transgene was flanked on both sides by two 239-bp GC-rich core fragments of the chicken β-globin insulator to minimize position effects of DNA sequences surrounding the transgene and improve the gradual extinction of the reporter expression. In addition, as the basic vector, we used pGL4....
Sex determination system is essential not only for the study of reproductive biology and the process of genome evolution [5,42], but also for the development of sex manipulation techniques, especially in economically important species with obvious sexual dimorphic characters such as mud crab. Given ...

Once you've calibrated your understanding of human sexuality in males, it is an easy matter to understand female sexuality a bit differently than it is usually framed in evolutionary biology. In the old model, male orgasm was a simple delivery system for sperm. In pop-level evolutionary biology...
In the chicken two satellite DNA repeat families alone are estimated to correspond to E75% of the W chromosome, with other amplified repeat families contributing to the remaining sequence8. A small effective population size (Ne) and the sensitivity to selection that follows from absence of ...
FLAG tag-free versions of the fcMISv1 and fcMISv2 transgenes were cloned into AAV packaging plasmids that included a strong CMV enhancer, a ubiquitous chicken β-actin pro- moter, a synthetic intron, and a terminating 3'UTR with a rabbit β- globin polyadenylation signal for efficient ...
