In mammals, the bipotential gonad appears to be moved into the female pathway (ovary development) by the Foxl2, Wnt4, and Rspo1 genes.

In mammals, the bipotential gonad appears to be moved into the male pathway (testis development) by the Sry gene (on the Y chromosome), which triggers the activity of Sox9.
