Fig. 5From: Hybrid origin of European Vipers (Vipera magnifica and Vipera orlovi) from the Caucasus determined using genomic scale DNA markersD-statistics (A) and admixture proportions, f, (B) estimated for each taxon included as the P2 group in ABBA/BABA tests. Nonzero D-statistics and admixture proportions indicate a history of introgression between the P2 group and V. renardi, which was assigned as the donor P3 group in each test.
