IBD sharing between siblings without and with runs of homozygosity (ROH). A Schematic of chromosomes for two parents (Par1, Par2). B Schematics of recombinant chromosomes of two children (Sib1, Sib2). C Expected differences between Sib1 and Sib2 (p) along the chromosome. In both cases, p can take values of \(p_0\), \(p_1\) or \(p_2\), which are the expected proportions of differences in IBD states 0,1 and 2, respectively. D–F Same as A–C, except parent 1 is assumed to be homozygous
