potency. Incidentally, it implies that gonadal differentiation means reduction
in bisexual potency into unisexual potency in germ cells supporting somatic
cells.
Incidentally, dietary administration of androgen to masculinize
gravid female with differentiated ovary and gestating embryos with
undifferentiated gonad provides unique opportunity to test whether or
not the gonadal differentiation induces the loss of bisexual potency of germ
