WebLinkage Disequilibrium Coe cient Can similarly show that D Ab = D AB and D ab = D AB LD is a property of two loci, not their alleles. Thus, the magnitude of the coe cient is important, not the sign. The magnitude of D does not depend on the choice of alleles. The range of values the linkage disequilibrium coe cient can take on varies with ...
