  • These are the six genotype frequency classes that arise from n = 2 generations of potential interbreeding. Gg,2, Gg,1, and Gg,0 are the expected frequencies of loci having 2, 1, or 0 genes originating from species A, as described in the text. The final column gives names that we use to refer to these genotype frequency classes.
