Vedclass · Answer

(B) The process of oogenesis involves the formation of a mature female gamete. During the first meiotic division (meiosis $I$),the primary oocyte ($46$ chromosomes) undergoes unequal division to form a large secondary oocyte and a small first polar body. Since meiosis $I$ is a reductional division,the chromosome number is halved. Therefore,the secondary oocyte contains $23$ chromosomes (haploid state).
