Fig. 4

Allele frequencies of five missense mutations in populations along the Norwegian coast. Three missense mutations identified in selective sweeps on Chr 5 and two on Chr 25 were used in a genotyping assay of Atlantic salmon populations along the Norwegian coast. The graphs show frequencies of the reference alleles. River numbers are explained in Fig. 1. SNPs on Chr 5 included missense mutations in the genes nkrf, nkap and zbtb33 (green lines) and missense mutations on Chr 25 were located in the mx1-1 gene (blue lines)
