Detailed explanation-2: -Spermatogonia are diploid cells that have 46 chromosomes. Therefore the spermatids will have 23 chromosomes.
Detailed explanation-3: -In testis, the immature male germ cells (spermatogonia) produce sperms by spermatogenesis that begins at puberty. The spermatogonia (sing. spermatogonium) present on the inside wall of seminiferous tubules multiply by mitotic division and increase in numbers. Each spermatogonium is diploid and contains 46 chromosomes.
