Biology recombination
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 … 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 …
