Fig. 4From: Genetic polymorphisms of pharmacogenomic VIP variants in the Mongol of Northwestern ChinaLinkage disequilibrium analysis of the VDR in each of the twelve populations. LD is displayed by standard color schemes with bright red for very strong LD (LOD > 2, D ′ =1), pink red (LOD > 2, D ′ <1), blue (LOD < 2, D ′ = 1) for intermediate LD, and white (LOD < 2, D′ <1) for no LDBack to article page
