Inversions contribute disproportionately to parallel genomic divergence in dune sunflowers.

ABSTRACT: The probability of parallel genetic evolution is a function of the strength of selection and constraints imposed by genetic architecture. Inversions capture locally adapted alleles and suppress recombination between them, which limits the range of adaptive responses. In addition, the combined phenotypic effect of alleles within inversions is likely to be greater than that of individual alleles; this should further increase the contributions of inversions to parallel evolution. We tested the hypothesis that inversions contribute disproportionately to parallel genetic evolution in independent dune ecotypes of Helianthus petiolaris. We analysed habitat data and identified variables underlying parallel habitat shifts. Genotype-environment association analyses of these variables indicated paral
