^aH, mean genetic diversity; I^S_A, standardized index of association; P_MC, significance of obtaining this value in 1,000 Monte Carlo simulations; V_D, variance of pairwise differences; L, 95% critical value for V_D; V_D > L indicates linkage disequilibrium; Y, yes; N, no.

^bConsidering each group of specimens with the same multilocus genotype (MLG) as one individual.
