Question #a72a0

Answer 1

A primary oocyte will undergo cell division (meiosis I) which results in one secondary oocyte and one polar body.

Explanation:

The process of forming a mature egg cell (ovum) involves several steps as depicted in the image below.

1. An oogonium grows and matures into a primary oocyte;
2. In the first fase of meiosis the primary oocyte will divide into a secondary oocyte and a first polar body. Polar bodies usually do not have the ability to be fertilized and will not develop further.
3. In the second fase of meiosis only the secondary oocyte will divide further into an ootid and a second polar body.
4. Only the ootid will finally form an ovum (mature egg cell) that can be fertilized.
