  • a The measure of linkage disequilibrium is performed by testing the null hypothesis (H0), VD = Ve, where VD is the variance calculated from the distribution of mismatch values of variance and Ve is the variance expected for linkage equilibrium. P values are derived from the parametric and simulation methods and indicate the significance of linkage disequilibrium. A P value must be <0.05 for hypothesis rejection.
