a Patterson’s D-statistic (± s.e.) amongst chromosomes. The dark blue line indicates no deviation from the true evolutionary history topology [(((Central wildcat, Western wildcat), domestic cat), outgroup)]; the light blue colored line indicates genome-wide D-statistic; black circles indicate significant deviation from 0 (Z-score > 3–4); and red triangles indicate non-significant deviations from 0 (Z-score < 3–4); b number of ABBA and BABA sites across SNPs in 10 Mb sliding windows
