Variant distribution across the genome. a SNV density in 50-kb windows, drawn from 1987 samples. Increased SNV density is observed at the X-PAR region and the ends of most autosomes. b Median copy number (CN) for 1824 dogs reveals a large, common duplication on chr9 relative to the reference genome. c Principal component (PC) analysis separates dog and wolf samples along the first axis while axis two separates dogs from Eastern and Western Eurasia. d SNV sharing between the three categories of samples
