Phylogenetic relationships between eight British cattle breeds. Genetic distances were calculated from allele frequency data of 30 microsatellite markers using (a) Nei's standard genetic distance (Nei, 1987) and (b) negative log of proportion of shared alleles (psa) values (Bowcock et al, 1994; Rosenberg et al, 2001). Phylogenetic relationships were reconstructed using NJ (Saitou and Nei, 1987) with 1000 bootstraps. Bootstrap values greater than 50% are shown in the figure.
