iv) Primary spermatocytes are haploid.
(correct answer + 1, wrong answer - 0.25)

• A. Only i and ii are correct.
• B. i, ii and iii are correct.
• C. Only i is correct.
• D. Only ii and iii are correct.

Answer 1

The correct option is A Only i and ii are correct.

The formation of sperms also called spermatogenesis begins at puberty.

Undifferentiated primordial germ cells undergo mitotic division to produce spermatogonia in testis. Each spermatogonium grows to a large primary spermatocyte by obtaining nutrients from the nursing sertoli cells.

The DNA content remains the same (2n), i.e., both spermatogonia and primary spermatocyte are diploid.
