Relatedness plot for thousand genomes samples. Each dot represents a pair of samples. IBS0 on the x-axis is the number of sites where 1 sample is homozygous for the reference allele and the other is homozygous for the alternate allele. IBS2, on the y-axis, is the count of sites where a pair of samples were both homozygous or both heterozygous. Points with IBS0 of 0 are parent-child pairs. The 4 points with IBS0 > 0 and IBS0 < 450 are siblings. There are also several more distantly related sample pairs
