A microsatellite-based method for genotyping diploid and triploid water frogs of the Rana esculenta hybrid complex
Research output: Contribution to journal › Journal article › Research › peer-review
Rana esculenta is a hybrid between Rana lessonae (LL) and Rana ridibunda (RR), and hybrids may be diploid (LR) or triploid (LLR or LRR). Genotypes can be roughly determined from erythrocyte size and morphometry in adult frogs, but accurate genotyping requires more labourious methods. Here I demonstrate that both the L and R genomes have specific microsatellite alleles, and that genotype and ploidy can be accurately inferred from the quantitative ratio of PCR-amplified (polymerase chain reaction-amplified) genome-specific alleles. This method greatly facilitates genotyping in DNA studies of the R. esculenta complex and allows analysis of badly preserved samples and embryos.
