| Abstract: | Summary The gynogenetic offspring of the hybrid frogRana esculenta (R. ridibunda x R. lessonae) are exclusively of theridibunda type. This is due to the premeiotic exclusion of thelessonae genome from the hybrid's germ cells.Acknowledgments. Prof. M. Fischberg, Genève, and Prof. P. Vogel, Lausanne, provided laboratory facilities.
