Posterior probabilities of aligned positions being classified as slowly evolving for VWF. Horizontal lines next to each name represent the aligned sequence, with gaps indicated by disruptions to the line (indels disrupt the von Willebrand Factor [VWF] A3 domain). Annotations for a sequence are displayed above its line. Red diamonds are single nucleotide polymorphisms (SNPs) annotated as being associated with von Willebrand disease, blue diamonds are the remaining SNPs. The blue line is the posterior probability a site belongs to the slow (bin0) bin.
