How many mature sperm cells are produced from a single spermatogonium during spermatogenesis?
Answer
Four mature sperm cells
The correct answer is Four mature sperm cells — Spermatids differentiate into spermatozoa, so one spermatogonium ultimately yields four mature sperm cells.
Step-by-step solution
- A spermatogonium undergoes mitosis to produce primary spermatocytes.
- Each primary spermatocyte divides by meiosis I to form two secondary spermatocytes.
- Each secondary spermatocyte divides by meiosis II to produce two spermatids, giving a total of four spermatids per primary spermatocyte.
- Spermatids differentiate into spermatozoa, so one spermatogonium ultimately yields four mature sperm cells.
Common mistake: Assuming one spermatogonium gives only one sperm
Concept tested: Outcome of spermatogenesis
