highly significantP < 2.2e-16
In the wild fish, as well as in the Nadia strain, the chi-square P values are highly significant ( P < 2.2e-16), and one sees a clear bias in favor of G/C to A/T for the low-frequency class alleles and a bias in favor of A/T to G/C for alleles occurring at high frequencies, both expected under gBGC ( Glemin et al. 2015 ).
