What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Marizza181 [45]

Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.

<h3>What is crossing over?</h3>

Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.

It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.

It actually occurs at the pachytene stage of prophase I of meiosis cell division.

Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.
