Figure 2

Genotype visualisation screenshot. A portion (3p14 – 7p15) of the genotype variation of 20 subjects is displayed. Each column, numbered 1 – 20, represents one DNA sample. In this example, to visualise LOH regions better, yellow was assigned to heterozygous genotypes and black was assigned to both homozygous genotypes. The LOH regions are highlighted by the arrows, and their number and extension are correlated with population demography.
