WebAug 17, 2024 · How does meiosis contribute to genetic variation in a cell? Meiosis is recognized as a process that contributes to genetic variation. Here’s a brief overview: There are two divisions that occur during the entire process of meiosis, ending in haploid cells. You start with a diploid (2n) cell, and end with 4 (n) haploids. WebMar 6, 2024 · It is the specific processes of meiosis, resulting in four unique haploid cells, that result in these many combinations. This independent assortment, in which the chromosome inherited from either the father or mother can sort into any gamete, produces the potential for tremendous genetic variation.
