Abstract
Electrophoretic variants of seven loci (Pgi, Mpi, Pgm-1, Pgm-2, Aat-1, Np and Odh) have been screened, in all possible pairwise combinations, in laboratory crosses of Littorina saxatilis. Two loci, Pgi and Np, are shown to be linked with a maximum likelihood recombination frequency of 0.30. Recombination occurs in both males and females. No strong evidence for linkage between other pairs of loci, including miscellaneous comparisons involving seven additional loci (Aat-2, Idh-1, Idh-2, Lap-1, Ap-2, Apk and Hdh), was obtained. Variants at all 14 polymorphic loci segregate in a Mendelian manner.
