Spermatogonia I. 23 chromosomes, undergoes meiosis II B. Primary spermatocyte II. 46 chromosomes, undergoes meiosis I C. Secondary spermatocyte III. 23 chromosomes, undergoes spermiogenesis D. Spermatid IV. 46 chromosomes, undergoes mitosis C

Step-by-step solution

Spermatogonia are diploid cells on the inside wall of seminiferous tubules containing 46 chromosomes, and they multiply by mitotic division. Some spermatogonia differentiate into primary spermatocytes, which are also diploid (46 chromosomes) and undergo the first meiotic division (meiosis I). Completion of meiosis I leads to the formation of secondary spermatocytes, which are haploid (23 chromosomes) and undergo the second meiotic division (meiosis II). This produces haploid spermatids (23 chromosomes), which do no
