They can hydroplane, where they lift part of their body out of the water and paddle with their webbed feet to generate forces that allow them to overcome gravity; they also use paddle-assisted flying, where the whole body is lifted out of the water, and the wings and feet work in concert to generate lift forces.

Most ducks had about the same amount of webbing on their feet as their parents. Individual differences or population differences can both be referred to as genetic variations. Thus genes are expressed together to produce a trait with continuous variability. Most of these have interdigital webbing, as opposed to the syndactyly found in birds. A:Organs apparently similar or dissimilar in structure and function but of similar embryonic origin, Q:Refer to this portion of a dichotomous key for fish identification to answer the question.
