Abstract: Genetic variation among samples of the M-line stock of Biomphalaria glabrata is described. Snail samples from 5 separate research laboratory facilities display differences in allozyme frequencies among 9 of 24 enzymes examined. Genetic variability of M-line snails is discussed relative to the origin and maintenance of the stock and its use as a model in studies of snail-schistosome interactions. Inquiries among investigators maintaining and using snails have indicated that multiple albino stocks of B. glabrata are or have been used for snail-schistosome research. Exchange of these stocks among investigators and subsequent interbreeding are the most probable explanations for the patterns of genetic divergence observed.
