recombination. Recombination in meiosis. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.In eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis.Meiosis is a form of cell division that produces gametes, or egg and sperm cells. During the first phase of meiosis, the homologous pairs of maternal and paternal chromosomes align.n eukaryotic cells, which are cells with a nucleus and organelles, recombination typically occurs during meiosis.
