Question: how many chromosomes are there in a human primary spermatocyte and a sperm?
Answer: Spermatocytes are a type of male gametocytes in human. There are two types of spermatocytes: primary spermatocytes and secondary spermatocytes. Primary spermatocytes are diploid cells which consist of 46 chromosomes in each cell. Each secondary spermatocyte contains 23 chromosomes because they are haploid cells.
