Question

A spermatogonium is a diploid cell with 46 chromosomes. Certain spermatogonia, known as primary spermatocytes, periodically undergo meiosis. When a primary spermatocyte completes the first meiotic division, it produces two equal haploid cells, called secondary spermatocytes, each containing 23 chromosomes. Which of the following correctly describes spermatogonium?

Accepted Answer

A spermatogonium is diploid and has 46 chromosomes.. A spermatogonium is a germ cell before meiosis, so it is diploid and contains the full human chromosome number, 46. Meiosis I reduces the chromosome number by half, producing haploid secondary spermatocytes with 23 chromosomes.
