Meiosis serves two purposes in life, one is to chromosomes by the other is to create diversity. two events happen during meiosis which to create genetic diversity. the first happens in prophase i and is called over.

Meiosis serves two purposes in life, one is to reduce the number chromosomes by half. the other is to create genetic diversity. Two events happen during Meiosis which help to create genetic diversity. The first happens in Prophase I and is called Crossing over.

Explanation:

A cell division type that helps in the chromosome reduction in the parent cell into 4 gamete cells is known as Meiosis. For sexual reproduction to take place this process is very essential for the production of sperm and egg cells. This process is required to produce egg and sperm cells for sexual reproduction.

These cells unite to form a single cell in which the chromosomes are restored. Crossing over is done to generate genetic diversity and the homologous chromosomes are positioned in a random manner. In this stage the number of chromosome is reduced from 2n to n.
