A_R, rarified allelic richness; H_O, observed heterozygosity; H_E, unbiased expected heterozygosity; Ne₀, current effective population size inferred as the intercept and related standard error as well as the slope of the regression (β₁); F_IS, inbreeding coefficient; CI, confidence interval (threshold values are showed in square brackets); for the full definitions of breeds (see Additional file 1: Table S1)
