Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Meiosis is also known as reductional division because the chromosomal number is reduced to half. Meiosis occurs in 2 stages meiosis 1 and meiosis 2. In meiosis 1 homologous chromosome pairs are separated resulting in the segregation of genes into the two gametes. There are 4 phases in meiosis I prophase 1, metaphase 1, anaphase1 and telophase 1. Meiosis creates gametes (egg and sperm cells). During meiosis, genetic information is exchanged between the maternally and paternally inherited copies of a pair of chromosomes in order to create new combinations of genes. This process of genetic recombination helps to increase genetic variability within a species.
So, the correct option is 'A'.
