Mating combinations resulting from the experimental crossing design with frogs from three ponds. We included three different individuals per genotype and cross in the experiment with the exception of pond 011, where only one LLR female was caught and one LR individual was initially falsely categorized as a LLR. A total of 120 crossings was carried out. Shaded areas are crosses done within a pond, white areas are crosses done between ponds
