Textbook Question
Chapter 39.2, Problem 2TYK
In which way is gametogenesis similar in males and females?
- The primary spermatocyte and primary oocyte both eventually produce four gametes.
- The formation of gametes includes both mitosis and meiosis in both sexes.
- The gametes in both sexes have a flagellum.
- The gametes that are produced are all diploid.
- In both sexes, meiosis is not completed until fertilization occurs.
