Final answer:
Adult African and Western clawed frogs exhibit sexual dimorphism, but without specific morphological details like tail length, sex identification relies on general amphibian biology and secondary sexual characteristics.
Step-by-step explanation:
In adult African and Western clawed frogs, sexual dimorphism allows for the differentiation between males and females without the need for genetic analyses or observation of croaking patterns. Although both sexes lack longfinned tails post-metamorphosis, certain characteristics can be used to identify males from females. In many frog species, males often have secondary sexual characteristics such as nuptial pads or differing coloration, though these specific traits are not mentioned in the provided information.
Additionally, frogs are known for their high fecundity, which typically implies a strategy of producing numerous offspring with the expectation that a relatively small number will survive to adulthood. In the absence of detailed information on specific morphological differences between the sexes in clawed frogs, such as tail length, it is difficult to provide an exact method for sex identification. However, researchers may apply their understanding of other species and general amphibian biology to guide their analyses of African and Western clawed frogs.
