  • Title: [A population genetics analysis of the structure of hybrid populations of Rana esculenta L. complex (Amphibia, Ranidae)].
    Author: Mezhzherin SV, Morozov-Leonov SIu.
    Journal: Tsitol Genet; 1993; 27(2):63-8. PubMed ID: 8212328.
    Abstract:
    Population-genetic analysis conducted in hybrid populations of Rana esculenta complex from neighbourhood of Kiev has shown a high portion of recombinant frogs within Rana esculenta specimens and limitation of gene flows from one species to the other. The mechanisms of limitations are connected with assortative crossings within R. ridibunda and R. lessonae and low viability of frogs with a recombined genotype.
