Last Answer : (i) Sectional view of human ovary. (ii) Morula is formed in the (a)Isthmus of the oviduct (Fallopiantube). (b)The zygote undergoes mitotic divisions in quick succession called cleavage, forming 2, 4 ... 8-16 blastomeres is called a morula and the inner cell mass gets ready to form the embryo proper.
Description : (i) When does oogenesis begin? (ii) Differentiate between the location and function of Sertoli cells and Leydig cells. -Biology
Last Answer : Oogenesis begins during the embryonic development stage when a million gamete mother cells (oogonia) are formed within each foetal ovary.
