Question

What is the chromosome count and ploidy level of a spermatogonium?

Options

• 46 chromosomes, diploid (2n)

• 46 chromosomes, haploid (n)

• 23 chromosomes, diploid (2n)

• 23 chromosomes, haploid (n)

Answer 1

A spermatogonium is a diploid cell containing 46 chromosomes (2n). These are the sperm mother cells present in the germinal epithelium of the seminiferous tubules that undergo repeated mitotic divisions during the multiplication phase to produce a large population of additional spermatogonia.
