Experimental test of the fitness effects of divergent marine-freshwater chromosomal inversions in stickleback under different salinity conditions.

Abstract excerpt

Chromosomal inversions are a type of structural variant that have long interested evolutionary biologists because of their potential role in local adaptation and speciation. However, direct experimental evidence for the fitness consequences of inversions is rare, limiting our ability to dissect the evolutionary forces associated with the spread and maintenance of inversions in natural populations. We tackle this...
