Question

What are the cells that secondary oocyte divides into called?

(a) Ovum and first polar body

(b) Ovum and second polar body

(c) First polar body and second polar body

(d) Primary oocyte and second polar body

I got this question in homework.

My doubt stems from Human Reproduction in chapter Human Reproduction of Biology – Class 12

Answer 1

Right choice is (b) Ovum and second polar body

Explanation: Secondary oocyte is formed as a result of the asymmetric division of primary oocyte, which also produces a tiny first polar body. Secondary oocyte further undergoes another asymmetric division producing a larger ovum and a smaller second polar body.
