Figure 2From: A human-specific allelic group of the MHC DRB1 gene in primatesDivergence times of HLA Group A and Patr-DRB1*03 alleles. The dashed line represents the speciation event of humans and chimpanzees. Times to most recent common ancestor (TMRCAs) were estimated based on the maximum genetic distance at synonymous sites (dSmax).Back to article page
