Final answer:
A secondary spermatocyte has a haploid number of chromosomes. It is produced during spermatogenesis when a primary spermatocyte undergoes meiosis I. The correct option is (B) secondary spermatocyte
Step-by-step explanation:
Among the options listed, the secondary spermatocyte has a haploid number of chromosomes. Spermatogenesis is the process by which sperm cells are created. During this process, spermatogonia undergo mitosis to produce two diploid cells, one of which remains a spermatogonium and the other becoming a primary spermatocyte. The primary spermatocyte then goes through meiosis I to produce two haploid secondary spermatocytes, each carrying half the number of chromosomes compared to the original diploid cells. The secondary spermatocytes quickly undergo meiosis II to produce spermatids, which are haploid as well. Eventually, these spermatids will develop into mature sperm cells, which are also haploid and carry only half the genetic information necessary to create offspring.
The correct option is (B) secondary spermatocyte
