NEET BIOLOGY

Detailed explanation-1: -Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA.

Detailed explanation-2: -Crossing over of homologous chromosomes in prophase I leads to an increase in genetic diversity because alleles get separated and combined differently. The segregation of chromosomes in meiosis is random and this increases genetic diversity because chromosomes are basically being shuffled like a deck of cards.

Detailed explanation-3: -Mitosis builds a person with an identical set of chromosomes in every cell. And meiosis generates reproductive cells with new combinations of gene variations.

Detailed explanation-4: -Genetic variation is introduced in multiple ways, including changes in mitosis, crossing over and random orientation in meiosis, and random fertilization.
