Figure 4 : Population genomics summary statistics of North Atlantic Harbour porpoises. (a) Individual genome-wide heterozygosity, each sample is coloured according to its sampling locality, admixed individuals are coloured in purple and migrants were not included. (b) Individual inbreeding coefficient for each sample. (c) Violin plots of Tajima’s D values estimated at population/location level with a sliding-window approach with window size of 50 kb and a step size of 10 kb; the white dot indicates the mean value across the 50 kb Windows. No Tajima’s D was calculated for the Iberian subspecies due to small sample size (n =1).
