Scatterplot showing the relationship between global genetic ancestry q estimated using 133 biallelic loci fixed for different alleles in parental species V. kaznakovi and V. renardi and the inter-source population ancestry for these loci Q12 [48]. Symbols correspond to individuals. Lines indicate the maximum level of inter-source population ancestry given global genetic ancestry q (solid lines) and the expected levels of Q12 if the hybrid population is in Hardy-Weinberg equilibrium (dashed line). These results provide no evidence for ongoing gene flow from the parental groups V. kaznakovi and V. renardi to the proposed hybrid groups V. magnifica and V. orlovi
