| Abstract: | Dreissenids display a high diversity of shell morphology, and it is frequently difficult to ascribe some individuals from
mixed populations to one of the two species, Dreissena polymorpha (Pallas, 1771) or D. bugensis (Andrusov, 1897). Presumably, such individuals may be interspecific hybrids. We have analyzed species-specific allozyme loci
of the typical representatives of these two mussel species and putative interspecific hybrids. A natural interspecific hybrid
between D. polymorpha and D. bugensis was discovered for the first time by genetic methods. It has been demonstrated that D. bugensis was a maternal parent. |
