 || 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.

	descent of the kidneys and adrenal glands
	none of the above

9 The genital tubercle and inner genital folds form the same adult structures in both sexes.

	true
	false

10 Select the correct options below describing aspects of gonad development

	testis cortical and ovary medullary
