Question

What are the cells that primary oocyte divides into called?

• A. Secondary oocyte and first polar body
• B. Secondary oocyte and second polar body
• C. First polar body and second polar body
• D. Primary oocyte and second polar body

Answer 1

Answer:

A. Secondary oocyte and first polar body

The primary oocyte is arrested at Prophase I of meiosis, and the division is completed only in the tertiary follicle. This division is asymmetric and produces a large haploid secondary oocyte and a small first polar body.
