Question

What is the chromosome count of a secondary spermatocyte?

Options

• 23 chromosomes, haploid (n)

• 46 chromosomes, diploid (2n)

• 23 chromosomes, diploid (2n)

• 46 chromosomes, haploid (n)

Answer 1

A Secondary Spermatocyte is a haploid cell containing 23 chromosomes (n). These cells are produced when a Primary Spermatocyte undergoes Meiosis I (the reduction division). Two Secondary Spermatocytes are formed from each Primary Spermatocyte, each containing half the chromosomes of the parent cell.
