From: An original phylogenetic approach identified mitochondrial haplogroup T1a1 as inversely associated with breast cancer risk in BRCA2 mutation carriers

Figure 1

Simplified representation of the phylogenic method used to infer haplogroups. (a) Full-length haplotypic sequences are reconstructed at each node of the reference tree. (b) Haplotypes are then restricted to available loci. Sequences of the same color are identical. (c) Unique short haplotypes are matched directly with the corresponding haplogroup. (d) Sequences that match with several haplogroups are associated with their most recent common ancestor haplogroup. RSRS, Reconstructed Sapiens Reference Sequence.
