Clonal Variability of Limax flavus (Pulmonata, Limacidae): Allozyme, Karyologycal and Morphological Analysis. Garbar A. V., Chernyshova T. N. – As a result of allozyme variability analysis, populations of Limax flavus (Linnaeus, 1758) are shown to have clonal structure, typical for parthenogenetic species. The absence of intermediate genotypes, coexistence and morphological separation of clones confirm their reproductive isolation. Formation of haploid cells (n = 31) in meiosis, indicates the reproduction by mei- otic parthenogenesis. K e y wo r d s: Limax flavus, allozyme variability, clone, karyotype, morphology.
