in several populations, SNPs were genotyped for the major histocompatibility class (MHC) II region in a large number of human couples. Each individual was compared with another random individual of the opposite sex and a mean relatedness coefficient calculated, where a positive value indicates more related than average. This was repeated 100,000 times and the results were plotted as a blue histogram for each population. The mean measure
