Figure 5: Dendrogram constructed by the neighbor-joining method (a) relationships of the West Central India (WCI populations with other nine populations based on the allelic frequencies of human leukocyte antigen (HLA) HLA-A locus; (b) relationships of the WCI population with other 9 populations based on the allelic frequencies of HLA-B locus; (c) relationships of the WCI population with other 8 populations based on the allelic frequencies of HLA-DRB1 locus; and (d) relationships of the WCI population with other 7 populations based on the combined allelic frequencies of HLA-A, B and DRB1 loci
