Question

In humans, what does oogenesis produce?

O 1 functional egg with 46 chromosomes
O 1 functional egg with 23 chromosomes
O 4 functional eggs with 23 chromosomes
4 functional eggs with 46 chromosomes

Answer 1

Oogenesis is the process of producing eggs in the ovaries of a female fetus. It begins with a diploid oogonium dividing into a diploid primary oocyte. The primary oocyte goes through meiosis I and II to produce a single functional egg with 23 chromosomes.

Step-by-step explanation:

Oogenesis is the process of producing eggs in the ovaries of a female fetus. Oogenesis begins when a diploid oogonium divides by mitosis to produce a diploid primary oocyte. The primary oocyte begins meiosis I and then remains at this stage in an immature ovarian follicle until after birth. During oogenesis, the diploid primary oocyte undergoes meiosis I to form a haploid secondary oocyte. The secondary oocyte then completes meiosis II to produce a single functional egg with 23 chromosomes. The other three haploid cells produced during meiosis II, known as polar bodies, eventually degrade.
