Fig. 3
Total number of runs of homozygosity (ROHs) and proportion of ROH size classes in sampled gray whale genomes. Shown for each individual is the number of ROHs in each size class (a), with an insert showing the 1-160Kb ROH length categories in detail) and the sum of ROH lengths (Mb) in the genome (b). A Kolmogorov–Smirnov test indicated that the pairwise comparisons of ROH frequency distributions between were significantly different from each other (WGW1 & EGW D = 0.186, p = 2.2 × 10− 16; WGW2 & EGW D = 0.322, p = 2.2 × 10− 16, and WGW1 & WGW2 D = 0.142 p = 2.2 × 10− 16), suggesting that there are significant differences in genealogical histories between individuals
