<prompt> In primary spermatocyte chromosome is-22X44XY22YNone of Above  <response>: Ans. B. 44XYa. Spermatogenesis - The spermatogonium 44XY undergoes mitotic division to form two primary spermatocytes largest germ cells.b. The primary spermatocytes 44XY undergo first meiotic division reductional division to form two secondary spermatocytes. The secondary spermatocytes thus have haploid number of chromosomes.c. Each secondary spermatocyte 22XY immediately undergoes second meiotic division to form two spermatids 22XY.d. Thus, four haploid spermatids are produced from the meiotic division of one primary spermatocyte. The spermatids are small cells of about half the size of the secondary spermatocyte, and have round and darkly stained nuclei.e. Each spermatid gradually changes its stage to become spermatozoon or sperm. This transformation of circular spermatid into an elongated spermatozoon is called spermiogenesis.
