GENETIC STUDIES OF ALLOZYME VARIATION IN LEUCINE AMINOPEPTIDASE IN THE LAND SNAIL HELIX ASPERSA (MULLER)

In the land snail H. aspersathe enzyme LAP has two loci, LAP-1and LAP-2, both of which arc monomeric enzymes under the controlof multiple alleles, the alleles being codominant. None of theobserved ratios in the pheno types in the experimental progenywere significantly different from Mendelian expectation. ^* Present Address: Bournside School, Cheltenham, Glos.
