WebThe process of crossing over was used in genetic mapping to understand the order of genes on a chromosome, and to determine the distance between them. This works on the basis that if two genes are present far apart on the chromosome, the frequency of crossing over between the two will be greater. WebAlleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-overoccurs when two homologous chromosomes exchange genetic material during meiosis I. The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over.

WebApr 7, 2024 · Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool.
