Average coancestries (f_ii) and Nei’s genetic distances (D_Nei), contributions to global coancestry (f) and to average Nei’s distance (D), global coancestry (GDT|i) and proportional loss or gain in genetic diversity after removing each breed group, proportional contributions (PC) to a pool of maximum genetic diversity weighted and unweighted by sample sizes are shown; values for the five breed groups with the highest contributions are shown in bold, except for GDT|i and loss/gain for which only the two highest values; breeds in each group are defined in Table 1; ¹average coancestries weighted by sample sizes; ²average coancestries estimated by ignoring sample sizes; mean coancestry within-groups, f = 0.241; mean Nei’s minimum distance in the metapopulation, D = 0.055; mean coancestry in the metapopulation, f = 0.205; global genetic diversity of the metapopulation, GDT = 0.795.
