text: 'Chromosomal inversions have long been recognized for their role in local
adaptation. By suppressing recombination in heterozygous individuals, they can
maintain coadapted gene complexes and protect them from homogenizing effects of
gene flow. However, to fully understand their importance for local adaptation
we need to know their influence on phenotypes under divergent selection. For this,
the marine snail Littorina saxatilis provides an ideal study system. Divergent
ecotypes adapted to wave action and crab predation occur in close proximity on
intertidal shores with gene flow between them. Here, we used F2 individuals obtained
from crosses between the ecotypes to test for associations between genomic regions
and traits distinguishing the Crab‐/Wave‐adapted ecotypes including size, shape,
shell thickness, and behavior. We show that most of these traits are influenced
by two previously detected inversion regions that are divergent between ecotypes.
We thus gain a better understanding of one important underlying mechanism responsible
for the rapid and repeated formation of ecotypes: divergent selection acting on
inversions. We also found that some inversions contributed to more than one trait
suggesting that they may contain several loci involved in adaptation, consistent
with the hypothesis that suppression of recombination within inversions facilitates
differentiation in the presence of gene flow.'
