Multiple sources of reproductive isolation in a bimodal butterfly hybrid zone

An important evolutionary question concerns whether one or many barriers are involved in the early stages of speciation. We examine pre? and post?zygotic reproductive barriers between two species of butterflies (Heliconius erato chestertonii and H.?e.?venus ) separated by a bimodal hybrid zone in th...
