highly significantp -value < 0.0001
For the 50 BF 0.99 SNPs, F ST estimates between pairs of colour morphs were highly significant ( p -value < 0.0001) (Additional file 2 : Table S2), with the highest genetic differentiation between TRI and MAR ( F ST = 0.2145), intermediate between TRI and TYP ( F ST = 0.2125) and the lowest between MAR and TYP ( F ST = 0.1787) (Additional file 2 : Table S3).
