Supplementary material from Heterosis counteracts hybrid breakdown to forestall speciation by parallel natural selection
In contrast to ecological speciation, where reproductive isolation evolves as a consequence of divergent natural selection, speciation by parallel natural selection has been less thoroughly studied. To test whether parallel evolution drives speciation, we leveraged the repeated evolution of benthic and limnetic ecotypes of threespine stickleback fish and estimated fitness for pure crosses and within-ecotype hybrids in semi-natural ponds and in laboratory aquaria. In ponds, we detected hybriddoi:10.6084/m9.figshare.19615963.v1 fatcat:36kho7oo5ne7thm5aonjbw26zy
