Textbook Question
Chapter 46, Problem 7TYK
Which of the following statements correctly describes how the production of human sperm and eggs differs?
- a. The meiotic production of gametes occurs before a female is born but does not begin until puberty in males.
- b. Meiosis occurs in the testes of males but in the oviducts of females.
- c. Primary oocytes stop dividing by mitosis before birth, whereas male primary spermatocytes continue to divide throughout life.
- d. Meiosis is an uninterrupted process in males, whereas in females it resumes when a follicle matures and is only completed when a sperm penetrates the egg.
