Cladogram from BRCA1 and BRCA2 haplotypes. a Phylogenetic tree for the ten canonical BRCA1 haplotypes. b Phylogenetic tree for the ten canonical BRCA2 haplotypes. Circles represent different haplotypes with the diameters being proportional to the prevalence in this study. The distance between each circle is inversely proportional to genetic relatedness between haplotypes. The numbers in parentheses indicate how many of the polymorphisms differed between haplotypes
