Question

Which of the following statements concerning oogenesis is false?

A) Oogenesis begins before birth.
B) Ova develop from stem cells called oogonia.
C) An ovum completes its last meiosis after it is fertilized.
D) About half the oogonia complete mitosis between birth and puberty.

Answer 1

Oogenesis is the process of producing eggs in the ovaries of a female and is completed after fertilization. Oogonia develop into primary oocytes through mitosis, which then undergo meiosis to form secondary oocytes. An ovum completes its last meiosis after it is fertilized.

Step-by-step explanation:

Oogenesis is the process of producing eggs in the ovaries of a female. It begins before birth and is completed after fertilization. Oogonia, which are stem cells, develop into primary oocytes through mitosis.

The primary oocytes then undergo meiosis to form secondary oocytes, which develop into mature gametes called ova. It is important to note that an ovum completes its last meiosis after it is fertilized, not before. Therefore, statement C is false.
