Question

What Is The Advantage Of Arresting Meiosis In Oogenesis?

Answer 1

Oogenesis:

1. It is the process in which female gametes that is ovum are formed.
2. It is formed under 3 stages: multiplication, growth, and maturation stage.

Meiosis:

1. The reason for halting egg at meiosis I during oogenesis is to decrease the number of chromosomes in the cell, making it haploid.
2. When a female reaches adolescence, her primary oocytes undergo meiosis I, resulting in the formation of secondary oocytes.
3. This will start a second meiotic division, but it will be halted for 24 hours. The fallopian tube is waiting for a sperm to meet.
4. If the egg combines with sperm, meiosis II is complete, and the ovum develops into a zygote.
5. If meiosis I is succeeded by mitosis but the sperm does not unite with it, clones or precise duplicates of the mother are created throughout time.
