Final answer:
In spermatogenesis, a primary spermatocyte goes through meiosis I and II to produce four haploid spermatids which will eventually mature into spermatozoa.
Step-by-step explanation:
The process by which a primary spermatocyte results in spermatids is called spermatogenesis. During this process, each primary spermatocyte undergoes two rounds of meiotic division to produce four haploid cells known as spermatids. The primary spermatocyte first divides into two haploid secondary spermatocytes during meiosis I. Each of these secondary spermatocytes then undergoes meiosis II to further divide into two spermatids, resulting in a total of four spermatids per primary spermatocyte. As spermatogenesis progresses, these spermatids will mature into spermatozoa.
