a Reconstruction of the mitochondrial phylogeny of 23 female Norfolk Island Polynesian founder descendants. The mitochondrial SNPs defining the branching are displayed on the tree. b Reconstruction of the Norfolk Island pedigree, based on available genealogical and genetic information (n = 1388). Four separate mitochondrial lineages have persisted and are present in the current day population (these are represented by red, pink, blue and light blue in the figure). c Major mitochondrial haplogroup frequencies as inferred from full mitochondrial genome sequencing in the Norfolk Island pedigree
