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

  1. A spermatogonium undergoes mitosis to produce primary spermatocytes.
  2. Each primary spermatocyte divides by meiosis I to form two secondary spermatocytes.
  3. Each secondary spermatocyte divides by meiosis II to produce two spermatids, giving a total of four spermatids per primary spermatocyte.
  4. 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
