Question

In the human body, the multiplication phase and formation of oogonia proceed:

A) after fertilization
B) at the beginning of puberty
C) at the end of puberty
D) during the embryonic period

Answer 1

Oogenesis, the process of egg production in females, begins before birth and continues until after puberty. It involves the division of oogonia through mitosis and subsequent meiosis to form mature eggs or ova. Hence the correct answer is option B

Step-by-step explanation:

Oogenesis, the process of egg production in the ovaries of females, begins before birth and continues until after puberty. It starts with the division of diploid oogonia through mitosis to produce primary oocytes. These primary oocytes undergo meiosis to form secondary oocytes, and if fertilized by a sperm, develop into mature eggs or ova.

During oogenesis, the cytoplasm is unequally distributed, resulting in the production of polar bodies which eventually break down. The remaining large cell completes meiosis II to become the mature ovum.

Hence the correct answer is option B
