Sexual differentiation of the embryo is normally determined by
Sexual differentiation of the embryo is normally determined by
- the number of chromosomes, with males having 22 pairs and females having an extra pair of XX chromosomes.
- the presence of two X chromosomes, which causes the primordial testes to degrade.
- the presence of one Y chromosome, which causes the primordial ovaries to degrade.
- the presence of the Y chromosome, which directs the undifferentiated gonads to develop into testes (when there is one X chromosome present as well). (correct)
- hormones produced by the placenta.
