Cooper · Answer 1

False

Explanation:

Primary spermatocyte is produced by mitotic division of spermatogonia cells not by meiosis 1 and thatswhy primary spermatocyte is dipploid ... Primary spermatocytes goes to Meiosis I and produce secondary spermatocytes. Secondary spermatocytes goes to meiosis II to produce round spermatids. Spermatids form the spermatozoa (a complete mature sperm cell).

Aj · Answer 2

False

Explanation:

At the beginning of the process of spermatogeneis (production of sperms), many cells in the seminefeorus tublues of the testis go through mitosis to form diploid Spermatogonia. These diploid spermatogia undergo mitosis, (not meioisis) and later differentiate to form diploid primary spematocytes

The beginning of secretion of reproductive hormones (testosterone) at puberty stimulated the diploid primary spermatocytes to undergo the first meiotic division (note not meiosis II) to produce haploid Secondary spermatocytes.

The haploid secondary spermatocytes go through second mitotic division to form haploid spermatids, which later differentiated to haploid spermtozoan, with DNA condense in then head.
