Define recombination frequency in biology

WebGenetic recombination refers to the rearrangement of DNA sequences by the breakage and rejoining of chromosomes or chromosome segments. It also describes the consequences of such rearrangements, that is, the inheritance of novel combinations of alleles in the offspring that carry recombinant chromosomes. Genetic recombination is … WebHowever, this is biology so there is a caveat: the phenomenon of crossing over helps to shuffle the alleles for genes located on the same chromosome. A crossover event between the locations of two genes on a chromosome results in genetic recombination, or new combinations of alleles on a chromosome.
