Identification of a single genomic region associated with seasonal river return timing in adult Scottish Atlantic salmon ( Salmo salar), using a genome-wide association study
Examination of the genetic basis of the timing of the return migration of Atlantic salmon (Salmo salar) to fresh water from the sea, a trait of economic and conservation interest, was carried out using a genome-wide association study. We examined genotype data of 52 731 single nucleotide polymorphic...
