Reticulate Evolution of Parthenospecies of the Lacertidae Rock Lizards: Inheritance of CLsat Tandem Repeats and Anonymous RAPD Markers

The genetic relatedness of several bisexual and of four unisexual Lacerta saxicola complex lizards was studied, using monomer sequences of the complex-specific CLsat tandem repeats and anonymous RAPD markers. Genomes of parthenospecies were shown to include different satellite monomers. The structure of each such monomer is specific for a certain pair of bisexual species. This fact might be interpreted in favor of co-dominant inheritance of these markers in bisexual species hybridogenesis. This idea is supported by the results obtained with RAPD markers; i.e., unisexual species genomes include only the loci characteristic of certain bisexual species. At the same time, in neither case parthenospecies possess specific, autoapomorphic loci that were not present in this or that bisexual species.
