Genetic divergence at the NAD +‐dependent malic enzyme locus in Atlantic salmon from Europe and North America
The distribution of genetic variation for NAD+ malic enzyme ( ME* ) polymorphism in the Atlantic salmon was assessed in both anadromous and resident populations. The analysis revealed a major allelic divergence between North America and Europe. The *80 variant occurred in 39 of 40 North American sam...

| Summary: | The distribution of genetic variation for NAD+ malic enzyme ( ME* ) polymorphism in the Atlantic salmon was assessed in both anadromous and resident populations. The analysis revealed a major allelic divergence between North America and Europe. The *80 variant occurred in 39 of 40 North American samples, ranging in frequency from 0 to 0.515. In contrast, it was detected in only three fish from two of the 35 European locations analysed. Eleven fish from two rivers in north‐west France had the * 110 variant. While heterogeneity among North American populations was significant, no regional differentiation was apparent and anadromous and resident salmon were not found to differ. |
