FIGURE 2
Visual representation of our two‐population, single epigenetic locus model. Individuals in habitat A have the epigenetic locus X induced to state Xaa, producing the white phenotype. There is migration at rate m from habitat A to B, wherein white Xaa individuals have fitness 1 − s relative to green Xbb individuals. White Xaa individuals then hybridize with green Xbb individuals, passing the epigenetic state a onto hybrid Xab offspring at rate v. Note, there are no crosses between Xaa migrants, since we assume m is small. Subsequent generations of Xab hybrids then undergo cycles of selection and reproduction, with relative fitness 1 − hs, as indicated by the dashed arrows

Reproductive isolation (RI) at a neutral locus with respect to recombination rate r with and epigenetic locus under divergent selection between two habitats, under different rates of intergenerational transmission (v) of epigenetic state. s = 0.25, m = 0.001, p = 1, q = 0

FIGURE 4
Example of a covariation matrix between methylation state at CpG dinucleotides and single‐nucleotide polymorphisms (SNPs). The orange tiles along the diagonal indicate interactions between SNPs and CpG sites adjacent to one another, whereas the vertical column of orange tiles indicates a single trans‐acting locus influencing the state of many CpG sites.
