Web1 Answer. Statistically, this is that the maximum mean recombination frequency is 50%. Recombination defined this way means that Gene A and Gene B from one chromosome are not 'together' on the same chromosome after recombination. That means that the recombination frequency is the probability of an odd number of recombination events … WebThe frequency of each will be (100 – 28)/2, which is 36%. rS and Rs are the recombinant gametes (the ones resulting from crossing over.

WebFeb 5, 2014 · To a first approximation cossing over events take place at random positions along the aligned chromosomes. Consequently the further two loci are apart, the more likely that there will be a crossing over event between them. Thus the recombination frequency can be used to measure the distance between two genetic loci (or genes).
