ResumoSummary The inheritance of alleles at ten enzyme loci of Stagnicola elodes (Lymnaeidae) was analysed by laboratory crosses. Alleles for alanine aminopeptidase (2 alleles), leucine aminopeptidase (2 alleles), aspartate aminotransferase (2 alleles), β-hydroxybutyrate dehydrogenase-1 (4 alleles), 6-phosphogluconate dehydrogenase (2 alleles), esterase-2 (2 alleles), esterase-3 (2 alleles), esterase-7 (2 alleles), esterase-13 (2 alleles) and esterase-18 (2 alleles) segregate in the F 2 generation according to Mendelian expectations. Contingency X 2 tests for linkage done on F 2 progeny from crosses between strains homozygous for alternate alleles at two loci showed that β-hydroxybutyrate dehydrogenase-1, esterase-13 and esterase-18 are presumably linked.
