Results from downsampling four ABC Islands brown bears, three Scandinavian brown bears, and four polar bears to 0.5X, 1X, 2X, 5X, and 10X coverage along the longest genomic scaffold, running HAPMIX and AD-LIBS on the four ABC Islands bears at each coverage depth, and comparing these runs to results obtained from running both programs on the full-coverage versions of the same individuals. Each line represents an individual ABC Islands bear and each color represents a specific low coverage/full coverage comparison. a: percent of full coverage calls recovered by running each program at low coverage. Values given are averages across the three ancestry states (homozygous polar bear, heterozygous, and homozygous brown bear). b: percent of low coverage calls that were correct, according to full-coverage calls. Values given are averages across the three ancestry states. Some points are missing because HAPMIX was unable to detect any polar bear ancestry at 0.5X coverage
