Nuclear DNA genealogy and maternal ancestry. Legend: a Whole genome NJ tree estimated from ~ 19 million autosomal SNPs. b Median joining haplotype network based on complete mitochondrial genome. Most nodes represent one individual, size of larger nodes corresponds to multiple individuals with identical haplotypes. The number of mutations is drawn as hatch marks along edges. In both (a) and (b) nodes that correspond to the northern breeds are colored in shades of blue and nodes corresponding to southern breeds are colored in shades of red. Internal nodes (black) are inferred ancestral sequences
