Fig. 6From: The distribution of runs of homozygosity in the genome of river and swamp buffaloes reveals a history of adaptation, migration and crossbred eventsEigenvectors on ROH-based genomic relationship matrix. Plot of the first two eigenvectors of the ROH-based genomic relationship matrix calculated using SNPs coded according to their occurrence in ROH longer than 4 Mb (red = river; turquoise = swamp). Solid line indicates the 95% confident interval; dotted line indicates the 99% confident intervalBack to article page
