From: A complex selection signature at the human AVPR1B gene
Genealogy of A VPR1B Ex1 (A) and Ex2 (B) haplotypes reconstructed through median-joining networks. Each node represents a different haplotype, with the size of the circle proportional to the haplotype frequency. Also, circles are color-coded according to population (yellow: AA, blue: EU, green: YRI, red: AS). Polymorphisms are shown in red, green, blue or black if they are nonsynonymous, synonymous, located in UTRs or introns, respectively.
