Sex determination system in birds is characterized by a homo-(Neognatae) and heteromorphic (Paleognatae) sex chromosomes. Heterogametic female (ZZ/ZW system). DMRT1 gene regarded as main male determining factor this group of animals. The question remains about the participation other factors (HEMOGEN, AMH etc.) appearance testis, role steroid hormones formation ovaries. Complete inversion not typical for species with genotypic (GSD), although effect estrogen metabolites noted birds. For...
The work was carried out by microinjections of an aromatase inhibitor letrozole, estrogen receptor modulator tamoxifen in incubated eggs Gallus g. domesticus, the first day incubation. It also used 5-azacytidine (5-AC) at same time. Injection progesterone before onset meiosis prophase 1 on 16 h Morphologically and histologically PCR, sex 17-day embryos controlled. According to information received microinjection letrozole caused almost a 100% inversion genetic males females, which is...
