Genetic recombination happens as a result of the separation of genes that occurs during gamete formation in meiosis, the random uniting of these genes … In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.
