Primary spermatocyte คือ
WebPrimary spermatocyte definition: Biology See under spermatocyte Meaning, pronunciation, translations and examples WebA primary spermatocyte is transformed into two secondary spermatocytes during meiosis I - these cells then in turn are converted into (1N) spermatids during meiosis II. The second meiotic division is rapid (and therefore very few secondary spermatocytes can be identified in histological sections).

Verified answer. Spermatocytes are a type of male gametocyte in animals. They derive from immature germ cells called spermatogonia. They are found in the testis, in a structure known as the seminiferous tubules. There are two types of spermatocytes, primary and secondary spermatocytes. Primary and secondary spermatocytes are formed through the process of spermatocytogenesis.
