In which of the following transmission, meiosis occurs?: (A) Primary to secondary spermatocyte, (B) Secondary spermatocyte to globular spermatid, (C) Germ cells to spermatogonium, (D) Spermatogonium to primary spermatocyte
Answer is A. Meiosis is a special type of cell division that reduces the number of chromosomes to the haploid number of 23 (from diploid number 46). It takes place in germ cells only; to give rise to gametes (sperms and egg cells) It involves two meiotic cell divisions, meiosis I & meiosis II.
