genomic architecture; genetic trade-off

Sažetak
A central tenet of adaptive evolution is the differential fitness of genotypes in different environments. Theory suggests that these fitness differences may arise from genetic variability that is beneficial in some environments but deleterious in others, yet evidence to support this genetic trade-off is scarce. In this study we conducted a field transplant experiment and recorded differences in survival of 900 transplanted Mytilus galloprovincialis mussels in different environments. We use these survival data as a proxy for fitness in a genome-wide association scan with ~20, 000 GBS variants. Our results show that fitness differs between environments and there is a genotypic signature involving around 60 genetic markers, but that these markers are different between environments. Our results challenge the hypothesis that adaptation involves genetic trade-offs. Implications of these data will be discussed.
