Ssa26/28 FISH-images with arrows pointing at BAC probes. Metaphase spreads of a male North American Atlantic salmon from Aqua Bounty Canada and a European Atlantic salmon. Red label: BAC S0059P02 on ssa26, Green label: BAC S0091M08 on ssa28. 1: European Atlantic salmon: The signals were found on different acrocentric chromosome pairs in the European sample. 2: North American Atlantic salmon: The signals were joined on a metacentric chromosome in the North American salmon (fusion of ssa26 and ssa 28) and on the two unfused acrocentric chromosomes (ssa26 and ssa28), indicating that this North American Atlantic salmon is heterozygous for the fusion.
