Abstract

The association of genetic markers linked to the sex-determining locus (SEX) was investigated in five Arctic charr Salvelinus alpinus full sib families, all originating from the Fraser River strain, Labrador, Canada. Two distinct sex-linkage classes were identified: type I (two families), with previously reported markers on linkage group 4 (AC-4) linked with SEX; and type II (three families), with two unlinked segments of the AC-4 linkage group, but with markers in only one cluster associated with SEX. Large differences in recombination rates, pseudolinkage assembly or various chromosomal rearrangements may explain these findings. © 2007 The Fisheries Society of the British Isles.
