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). 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.
