From: AD-LIBS: inferring ancestry across hybrid genomes using low-coverage sequence data
Geographic signal recovered in vectors of polar bear ancestry. a: principal components analysis (PCA) of polar bear ancestry state of 10kb genomic windows for 18 brown bears, using EIGENSOFT SmartPCA [24]. b: PCA of SNP data from a previous study [17], including a subset of the bears in a. Both plots show similar geographic patterns, with the Montana bear (GP01) falling close to the Admiralty Island bear(s), but only the SNP data separates Finnish (RF01) from Swedish brown bears
