  text: Chromosomal inversion polymorphisms, segments of chromosomes that are flipped
    in orientation and occur in reversed order in some individuals, have long been
    recognized to play an important role in local adaptation. They can reduce recombination
    in heterozygous individuals and thus help to maintain sets of locally adapted
    alleles. In a wide range of organisms, populations adapted to different habitats
    differ in frequency of inversion arrangements. However, getting a full understanding
    of the importance of inversions for adaptation requires confirmation of their
    influence on traits under divergent selection. Here, we studied a marine snail,
    Littorina saxatilis, that has evolved ecotypes adapted to wave exposure or crab
    predation. These two types occur in close proximity on different parts of the
    shore. Gene flow between them exists in contact zones. However, they exhibit strong
    phenotypic divergence in several traits under habitat-specific selection, including
    size, shape and behaviour. We used crosses between these ecotypes to identify
    genomic regions that explain variation in these traits by using QTL analysis and
    variance partitioning across linkage groups. We could show that previously detected
    inversion regions contribute to adaptive divergence. Some inversions influenced
    multiple traits suggesting that they contain sets of locally adaptive alleles.
    Our study also identified regions without known inversions that are important
    for phenotypic divergence. Thus, we provide a more complete overview of the importance
    of inversions in relation to the remaining genome.
