Isozyme variants in two natural populations of Lymnaea luteola

Lymnaea luteola is a fresh water gastropod snail, inhabiting ponds and lakes of different parts of India. Two populations of L. luteola were collected from fresh water ponds of district Varanasi (Uttar Pradesh) and analysed for their isozyme variants of Xanthine dehydrogenase (Xdh) and Aldehyde oxidase (Ao) enzymes loci. Both enzymes were found to be represented by two distinct loci and each locus of an enzyme showed polymorphic appearance. Based on the electrophoretic variant data, level of heterozygosity was computed for each enzyme locus. Our analysis clearly reveals that L. luteola inhabiting in these two ponds have undergone enough genetic differentiation. DOI: http://dx.doi.org/10.5281/zenodo.1045133
