WebJun 8, 2024 · Duplications can arise from unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The product of this recombination is a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombination is typically mediated by sequence similarity at the duplicate breakpoints, which form direct … Webrecombination: [noun] the formation by the processes of crossing-over and independent assortment of new combinations of genes in progeny that did not occur in the parents.
