Abstract excerpt

The molecular mechanisms underlying genome exclusion and clonal gamete formation in the germline of hybridogenetic water frog hybrids are poorly understood. Here, we characterize for the first time the coding sequences of 160 gametogenic genes from the European water frog species Pelophylax lessonae (LL) and Pelophylax ridibundus (RR). In addition, single nucleotide polymorphisms (SNPs) in 52 of these genes were...
