| Summary: | Efforts to understand the genetic underpinnings of phenotypic variation are becoming more and more frequent in molecular ecology. Such efforts often lead to the identification of candidate regions showing signals of association and/or selection. These regions may contain multiple genes and therefore validation of which genes are actually responsible for the signal is required. In Atlantic salmon (Salmo salar), a large‐effect locus for maturation timing, an ecologically important trait, occurs in a genomic region including two genes, vgll3 and akap11, but data for clearly determining which of the genes (or both) contribute to the association have been lacking. Here, we take advantage of natural recombination events detected between the two candidate genes in a salmon broodstock to reduce linkage disequilibrium at the locus, thus enabling delineation of the influence of variation at these two genes on early maturation. By rearing 5,895 males to maturation age, of which 81% had recombinant vgll3/akap11 allelic ... |
