WebMeiosis generates genetic variation in the diploid cell, in part by the exchange of genetic information between the pairs of chromosomes after they align (recombination). Thus, on this view, [28] an advantage of meiosis is that it facilitates the generation of genomic diversity among progeny, allowing adaptation to adverse changes in the ... WebWhen genes are on the same chromosome but very far apart, they assort independently due to crossing over (homologous recombination).This is a process that happens at the very beginning of meiosis, in which homologous chromosomes randomly exchange matching fragments. cockpit ms 406

One of the most notable examples of recombination takes place during meiosis (specifically,during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
