||Remember the anatomy of the adult gonads, with cortical primordial follicles in the ovary and medullary seminiferous tubules. The primordial germ cells in the testis form diploid spermatogonia that proliferate by mitosis and divide by meiosis postnatally. The primordial germ cells in the ovary form primordial oocytes that proliferate by mitosis and commence meiosis prenatally in the fetal ovary. | |||
