a BABA/ABBA analysis for introgression of dromedaries into domestic Bactrian camels. To focus on this introgression, one dromedary with the ancestry of Bactrian camels and three wild camels with the ancestry of domestic ones were removed. Number of 100 kb segments with significant fd (|Z-score| > 2) for each tree configuration is shown. b Neighbor-joining (NJ) tree of the populations after the introgressed segments were removed. The heatmap represents average pairwise Fst for 5.1 × 104 10 kb-sliding windows. Bootstrap values of the NJ tree were calculated by randomly sampling five thousand 10 kb windows for 100 times. c Maximum likelihood tree of full-length mtDNAs. Populations are represented by different colors and sequences from Genbank are indicated by dots. Bootstrap values for main branches are labeled.
