8.3: Meiotic Recombination - Biology LibreTexts

WebRecombination occurs when a piece of the paternal chromosome is swapped for the homologous piece of DNA on the matching maternal chromosome (or vice versa). Obviously, this kind of a DNA swap must be done carefully and with equivalence, so that the resultant DNA does not gain or lose information. Web28 oct. 2015 · The study of homologous recombination has its historical roots in meiosis. In this context, recombination occurs as a programmed event that culminates in the formation of crossovers, which are essential for accurate chromosome segregation and create new combinations of parental alleles.
