Question

spermatids possess haploid chromosomes number. explain?​

Answer 1

Answer:

Explanation:

• 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.
• Some of the spermatogonia called primary spermatocytes periodically undergo meiosis.
• A primary spermatocyte completes the first meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes, which have only 23 chromosomes each.
• The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids.
• The spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis.
• After spermiogenesis, sperm heads become embedded in the Sertoli cells, and are finally released from the seminiferous tubules by the process called spermiation.
