| Abstract: | A cytological and histochemical study has been made of Balbiani's vitelline body in the oocytes of nonvitellogenic and vitellogenic females of the domestic fowl (Gallus domesticus), which consists of yolk nucleus, mitochondria, Golgi bodies and lipid bodies of diverse nature. The yolk nucleus consisting of RNA, protein and lipoprotein shows the greatest development and morphological complexity in the growing oocytes of vitellogenic females. Its possible significance has been discussed in relation, to the variable metabolism and hormonal status of the female during sexual maturation. |
