In a laboratory study, $2,500$ spermatogonia are induced to undergo complete spermatogenesis. Assuming each spermatogonium gives rise to one primary spermatocyte, each primary spermatocyte yields two secondary spermatocytes, each secondary spermatocyte forms two spermatids, and each spermatid differentiates into a mature spermatozoon, calculate the total number of mature spermatozoa produced.

Step-by-step solution

1. Note that each spermatogonium produces one primary spermatocyte, so primary spermatocytes = $2,500$.
2. Each primary spermatocyte undergoes meiosis I to give two secondary spermatocytes; therefore secondary spermatocytes = $2\times 2,500=5,000$.
3. Each secondary spermatocyte undergoes meiosis II to produce two spermatids; thus spermatids = $2\times 5,000=10,000$.
4. Every spermatid differentiates into one mature spermatozoon, giving a total of $10,000$ mature spermatozoa.

Concept tested: Spermatogenesis yields four sperm per spermatogonium
