Solution

The correct option is B Primary spermatocytes undergo mitosis to produce secondary spermatocytes.

Spermatogenesis is the process in which haploid sperms are formed inside the testis.

Spermatogonia are immature diploid male germ cells present inside the seminiferous tubules of testis. They multiply by mitosis and are produced in large numbers during puberty.

Some of the spermatogonia undergo differentiation and form primary spermatocytes.

Primary spermatocytes are large diploid cells having 44 + XY chromosomes.

They undergo meiosis I to produce small sized haploid secondary spermatocytes of two types, 22 + X and 22 + Y.

Secondary spermatocytes divide by meiosis II to produce haploid spermatids.

From each primary spermatocyte two secondary spermatocytes are formed. Each secondary spermatocyte divides to form two spermatids. Hence, from one primary spermatocyte four haploid spermatids are formed.

Spermatids transform into sperms.
