Differences between MHC haplotypes and reference pgf. The new haplotypes and the seven alternative reference haplotypes were aligned to the reference pgf haplotype through pairwise alignment, and the percentage of pairwise differences was calculated in bins of 10 kb, shown here in white (low) to red (high). Dark gray bins contain >50% missing data (i.e., Ns); bins with red line lack alignment blocks. The region classes and important genes such as the classical loci are shown above. C4A and C4B are marked in blue.
