Figure 4 .

Genetic map of North American Atlantic salmon chromosome ssa08/29. The proposed chromosome is to the left and the corresponding European Atlantic salmon chromosome(s) to the right. Numbers correspond to SNPs listed in Additional file 1. SNPs in colors are shared between Atlantic salmon from both sides of the Atlantic Ocean. Red lines extend to the set of SNPs with limited recombination in the male map. The chromosome consists of the metacentric European ssa08 (red) fused with the acrocentric European ssa29 (green) tail to head, causing a predicted centromere shift to the fusion point. The new chromosome ssa8/29 is metacentric.
