WebThe Linkage Disequilibrium Coefficient D is one measure of LD. For biallelic loci with alleles A and a at locus 1;B and b at locus 2 , D is defined as ( Eq. 1 ): (1) LD is a property of two loci, not their alleles. Thus, the magnitude of the coefficient D is important and it does not depend on the choice of alleles.
