During a class on genetics for pregnant families, the nurse is discussing the how the egg and sperm are formed before fertilization takes place.

The nurse explains that these cells have only half the number of chromosomes, so when fertilization takes place, there will be the correct number. What is the process by which the egg and sperm are formed called? 1. Oogenesis
2. Gametogenesis
3. Meiosis
4. Spermatogenesis

Question 2

After explaining how meiotic division occurs within the ovum, the nurse knows that the pregnant patient understands when she states:

1. The second meiotic division is arrested until and unless the oocyte is fertilized..
2. Meiosis in the oocyte begins at puberty..
3. The first meiotic division continues when the female infant is born..
4. Fertilization does not take place in the secondary oocyte..

Explanation: 2. Gametogenesis is the process by which ovum and sperm are produced.

Answer to Question 2

1
Rationale 1: This is true. The second meiotic division is arrested unless fertilization takes place.
Rationale 2: Meiosis begins before the baby is born, but stops before the first division is complete, and remains in this arrested phase until puberty.
Rationale 3: The first meiotic division stops before the first division is complete, and remains in this arrested phase until puberty.
Rationale 4: The secondary oocyte is where fertilization will take place.
