WebApr 7, 2024 · Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. Homozygous chromosomes come side by side and they exchange genetic material during prophase of meiosis I. () Consider combined effects of all these to understand the impact of meiosis: … WebHowever, this is biology so there is a caveat: the phenomenon of crossing over helps to shuffle the alleles for genes located on the same chromosome. A crossover event between the locations of two genes on a chromosome results in genetic recombination, or new combinations of alleles on a chromosome.
