Gonadal sex and temperature independently influence germ cell differentiation and meiotic progression in Trachemys scripta

30 Dec 2024

Abstract excerpt

In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature-dependent sex determination (TSD). In the red-eared slider turtle,...
