A polar body is a small haploid cell that is formed concomitantly as an egg cell during oogenesis, but which generally does not have the ability to be fertilized. When certain diploid cells in animals undergo cytokinesis after meiosis to produce egg cells, they sometimes divide unevenly.

Polar body is haploid cell with no or negligible cytoplasm which prevent any metabolic activity and even make it unsuitable for fertilisation. Later it also dissolves.

Explanation:
Polar bodies:
- Polar bodies are the minute cells that separate from the developing ova during their maturation.
- They are produced during oogenesis, the process of egg cell formation in females.
- As the ova mature, they undergo two meiotic divisions to form a single egg cell and three polar bodies.
- The polar bodies contain genetic material but are not involved in fertilization.
- They eventually degenerate and are reabsorbed by the body.
Primary Oogonia and Secondary Oogonia:
- Primary oogonia are the precursor cells that give rise to ova in females.
- Secondary oogonia are the cells that result from the division of primary oogonia and undergo further development to become primary oocytes.
Importance of Polar Bodies:
- Polar bodies play a crucial role in ensuring the proper distribution of genetic material during oogenesis.
- They help in reducing the genetic material to half in preparation for fertilization.
- The formation of polar bodies also ensures that the egg cell has enough cytoplasm and nutrients to support the developing embryo after fertilization.
In conclusion, polar bodies are the minute cells that separate from the developing ova during their maturation. They are essential for proper genetic distribution and support the development of the embryo after fertilization.
