Answers
Answer:
hii
your answer is here !
Explanation:
a) Primary spermatocycte will also have 30 chromosomes because it is formed by mitotic division from spermatogonial cell.
b) The spermatid is produced by meiotic division (reductional division) from primary spermatocyte and will have only half (15) chromosomes.
The primary spermatocyte first undergoes meiosis I to produce two haploid secondary spermatocytes. The secondary spermatocytes undergo meiosis II to produce four haploid spermatids.
