What is Genomes of Two Water Frog Species Resist Germ Line Exclusion in Interspecies Hybrids about?
Abundant natural interspecies hybrids between the European water frog Rana ridibunda and at least three other taxa reproduce hemiclonally, by hybridogenesis: the non-ridibunda genome is excluded in the germ line before meiosis, and the unrecombined ridibunda genome is transmitted to haploid gametes. In contrast, natural hybrids between Rana ridibunda and either of two Balkan species (Rana shqiperica and Rana epeirotica) do not show such genome exclusion. This plausibly results from failure of Balkan Rana ridibunda genomes to "induce" such exclusion in the germ line of hybrids, from "resistance" of Rana shqiperica and Rana epeirotica genomes to such exclusion in hybrids with an "inducing" Rana ridibunda genome, or both. We tested the second hypothesis by examining lampbrush chromosome patterns in oocytes of hybrids that in the soma contain one "inducing" ridibunda genome and one genome of either of the two Balkan species. Several lampbrush chromosome markers (e.g., presence and location of certain giant loops and conspicuousness and width of centromeres) discriminate sets of Rana ridibunda chromosomes from those of Rana shqiperica and Rana epeirotica. Based on such markers, nine dip
