Multilocus basis of incipient reproductive isolation in hybridizing populations is revealed by pangenomic and epigenetic divergence

Incipient reproductive isolation in the presence of gene flow has traditionally been attributed to a small number of major-effect loci under strong selection. Here, using the Heliconius erato adaptive radiation, we apply a pangenome framework to examine how mutational divergence, regulatory variation, and structural va...
