Answer 1

Sexing frogs depends on the species. There are a number of tropical species that are dimorphic in regards to color, with the males being more colorful than females. In Minnesota, Bullfrogs and Green Frog males have larger eardrums than females. In some species males will have enlarged thumbs. Most good field guides will provide descriptions of the differences.
