[Genetic defects in inheritance and the variability of locus Ldh-B in hybrid populations of Rana esculenta complex (Amphibia, Ranidae)].
The directed ingression of Lhd-B gene from R. lessonae to R. ridibunda observed during hybridization between these species was confirmed in the present study. The ingression was accompanied by decreased of the initial allele activity, segregative disturbances in heterozygotes and changes in electrophoretic mobility. The population genetic analysis has shown stable preservation of abnormal alleles in hybrid populations. The results are discussed with reference to the concept of genetic instability, its application to speciation models, and the neutralist vs. adaptationist controversy. Our data supports the neutral concept of allozyme variation.
