In humans at the end of first meiotic division, the male germ cells differentiate into the

  • primary spermatocytes

  • secondary spermatocytes

  • spermatids

  • spermatogonia

Solution

B.

secondary spermatocytes

At sexual maturity, the undifferentiated primordial germ cells divide several times by mitosis to produce a large number of spermatogonia. Each spermatogonium then grows to a large primary spermatocyte. Each primary spermatocyte undergoes two successive divisions, called maturation divisions. The first maturation division is reductional or meiotic. Hence, the primary spermatocyte divides into the haploid daughter cells called secondary spermatocytes.
