Figure 6: Maturation threshold QTL location on linkage group LG25.

Marker locations are indicated in centimorgan, with in red the markers located within the QTL region. SNP sqSNP_22, sqSNP_24 and sqSNP_25, highlighted in bold, correspond to three SNP located on chromosome 25: respectively, a SNP without RefSeq reference located in position 28666061, rs863782897 located in position 28667099, both downstream Vgll3 gene, and rs863917458 located in position 28720779 within an intron of AKAP11 gene; these three markers were found, among others in the region, to be linked with sea age at maturation in anadromous Atlantic salmon31,32. These SNP were genotyped using a Sequenom array. lmSNP represents SNP genotyped using a Genotyping By Sequencing approach, markers beginning with IND are insertion-deletion and SSR identifies microsatellites.
