Which of the following is NOT true regarding spermatogenesis? * Some of the spermatogonia become reservoir cells. Spermatocyte undergoes two rounds of division to produce 4 diploid sperms. Spermatogonia breaks away from the basement membrane to develop into sperm. Initial spermatozoa formed are not mobile and cannot fertilize. Spermatogonia have diploid chromosome.
