A) the growth of spermatogonia into primary spermatocyte
B) the formation of spermatogonia from gonocytes through mitosis
C) the formation of spermatids from primary spermatocytes through meiosis
D) the formation of oogonia from the spermatocytes through meiosis
Correct Answer: C
Solution :
Spermatogenesis occurs in the seminiferous tubules of the testes. It includes three phases : [a] Multiplication phase : Undifferentiated primordial germ cells undergo repeated mitotic divisions and produce large number of sperm mother cells or spermatogonia. [b] Growth phase : spermatogonia grows to a larger primary spermatocyte. [c] Maturation phase : The primary spermatocytes undergoes meiosis to form four haploid spermatids.
