a Standardized linkage disequlibrium coefficient (absolute D' value) of Lewontin was shown.

b Significant levels based on the chi-squared distribution to test whether the disequilibrium value differs from zero (one degree of freedom). Bold and underline indicate no significant LD at the p < 0.05 level.
