Evidence of LOH observed in haplotype-phased chromosomes. Two examples of regions in which LOH is expected to have occurred in some strains. (A) The common ancestor of the strains is considered to have had hetero-SNVs in these regions, and some strains are suspected to have undergone LOH, thus switching SNVs from the hetero to the homo type. (B) In this block, nested LOH events likely occurred. This figure is available in black and white in print and in colour at DNA Research online.
