The sry gene involved in sex determination is
WebThe discovery that the SRY gene induces male sex in humans and other mammals led to speculation about a possible equivalent for female sex. But females are proving to be more complicated. Several master genes appear to be autonomously involved, and female sex determination seems to remain relatively labile. WebMammalian Sex Determination. In mammals, the sex of an individual is determined at conception. When a Y-bearing sperm fertilizes a X-bearing egg, the sex of the embryo is male while a X-bearing sperm will produce a female embryo. In the presence of the Y chromosome, specifically the sex-determining region Y (SRY) gene on this chromosome, …
