D)Degeneration of germ cells between fetal life and the onset of puberty

Question

Quizplus · Accepted Answer

In oogenesis the first meiotic cell division results in the unequal distribution of cytoplasmic fluid and all organelles into the secondary oocyte. As a result, the first polar body contains very little of these elements. By the end of meiosis II, only the mature ovum has cytoplasm. In spermatogenesis, the cytoplasm and all its elements are evenly distributed to the secondary spermatocytes (and eventually to the four spermatids). Synapsis occurs during the zygotene stage of both spermatogenesis and oogenesis. Chromatid elongation occurs in the leptotene stage. Degeneration of germ cells between fetal life and the onset of puberty occurs only in oogenesis.
