A total of 1683 individuals from 79 herds were sampled and genetic diversity within and among lineages was assessed using 24 microsatellite loci on 22 different chromosomes. Expected heterozygosity ranged between 0.46 and 0.68 per lineage and there was significant inbreeding in the lineages, which included several farms [mean F.sub.IS = 0.11, bootstrap 95% confidence interval (0.09, 0.14)], mainly because of the high genetic divergence between herds within those lineages. High genetic differentiation between lineages was also found with a mean F.sub.ST of 0.18 [bootstrap 95% confidence interval (0.17, 0.19)], and all pairwise values, which ranged from 0.07 to 0.35, were highly significant. The relationships among lineages showed weak statistical support. Nonetheless, lineages were highly discrete when analysed using correspondence analysis and a great proportion of the individuals were correctly assigned to their own lineage when performing standard assignment procedures.
