Fig 1. Rearing methodology and description of analyses.
(A) Within 12 hours after mating, we transferred foam nests to a container with 5cm deep rainwater. On the 5th day after the first tadpole hatched, we separated tadpoles into three rearing tanks containing 20 tadpoles each. (B) Table including the list of crosses used for each analysis with sample size for each group. Single numbers represent the total number of crosses for that group combination; numbers separated by a comma represent sample sizes for each cross type in the same order in which the cross types are presented.
