Several studies report significant LD over distances longer than those predicted by standard models, whereas some data from short, intergenic … 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.

This shows independence between the genes that control load for the two viruses. In general, the primary source of genetic correlation is pleiotropy, though linkage disequilibrium can be a contributing factor [71,72].
