Selection on outlier loci and their association with adaptive phenotypes in littorina saxatilis contact zones.
(2015) In Journal of evolutionary biology 28(2). p.328-337- Abstract
- A fundamental issue in speciation research is to evaluate phenotypic variation and the genomics driving the evolution of reproductive isolation between sister taxa. Above all, hybrid zones are excellent study systems for researchers to examine the association of genetic differentiation, phenotypic variation and the strength of selection. We investigated two contact zones in the marine gastropod Littorina saxatilis and utilized landmark-based geometric morphometric analysis together with amplified fragment length polymorphism (AFLP) markers to assess phenotypic and genomic divergence between ecotypes under divergent selection. From genetic markers we calculated the cline width, linkage disequilibrium and the average effective selection on a... (More)

From genetic markers we calculated the cline width, linkage disequilibrium and the average effective selection on a locus. Additionally, we conducted an association analysis linking the outlier loci and phenotypic variation between ecotypes, and show that a proportion of outlier loci are associated with key adaptive phenotypic traits.
