Real data–data set 2. (A) Distribution of D′ values observed between syntenic marker pairs as a function of genetic distance in centimorgan (cM). The red lines correspond to averageD′ values for marker pairs sorted in 5-cM bins (0–60 cM). (B) Frequency distribution of D′ values observed for all nonsyntenic marker pairs. (C) Cumulative frequency distribition of α-values. (Black) Pairs of syntenic markers; (red) pairs of nonsyntenic markers; (green) expected distribution under random allelic assortment.
