High-density linkage maps detail sex-specific regions of suppressed recombination near fusions of polymorphic chromosomes in purebred and hybrid North American Atlantic salmon (Salmo salar L.).

Abstract excerpt

The North American (NA) Atlantic salmon typically has 27 pairs of chromosomes, whereas the European (EU) subspecies typically has 29. We investigated within-family recombination within three previously identified chromosome rearrangements (Ssa01p/23, Ssa08/29, and Ssa26/28) in NA Atlantic salmon by creating high-density linkage maps using a custom 50K SNP chip developed for the Saint John River aquaculture...
