Table 1.
Composite genotype frequencies (%) of the Met55βVal and Lys62βAla replacement polymorphisms in Atlantic cod populations. (Double heterozygotes represent both coupling and repulsive heterozygotes, which were not distinguished by the SNP analysis. Numbers of fish are given in parentheses. See figure 4 for collection localities of cod samples.)
