Question

How does recombination contribute to evolution?

Answer 1

Contribution of recombination to evolution

1. Recombination is a process of producing new combinations of alleles by the recombination of DNA molecules.
2. This recombination process generates genetic diversity at the gene level, reflecting differences in DNA sequences between organisms.
3. Recombination occurs when non-sister chromatids of homologous chromosomes cross over.
4. It happens during the meiosis cell division's pachytene stage.
5. It generates variation, which is one of the factors that contribute to natural selection.
