<P> NR denotes the number of non-recombinant offspring , and R denotes the number of recombinant offspring . The reason 0.5 is used in the denominator is that any alleles that are completely unlinked ( e.g. alleles on separate chromosomes ) have a 50 % chance of recombination , due to independent assortment . ' θ ' is the recombinant fraction , i.e. the fraction of births in which recombination has happened between the studied genetic marker and the putative gene associated with the disease . Thus , it is equal to R / ( NR + R ) </P>
