During the creation of oocyte, 3 additional haploid cells are created that will not be fertilized these cells are called Polar bodies.
Explanation:
The process of formation of oocyte is known as the Oogenesis. The oogenesis is the formation of oocyte which is capable of being fertilized, and the process begins even before the birth of the child. The oogonia is a diploid cell which undergoes mitosis to form the primary oocyte.
The primary oocyte then undergoes first meiotic division forming the secondary oocyte. this secondary oocyte is haploid in nature and this would again undergo another meiotic division to produce 4 haploid daughter cells. One of these is haploid ovum with additional 3 cells which do not get fertilized. these additional haploid daughter oocyte cells are Polar bodies.

Tributary is the freshwater stream that falls into mainstream or river.
- It is usually made up of cold water as a result of snowmelt. When many tributaries enter into a river, they can change the temperature of the river water instantly.
