That has no bearing on the females selection of a mate. The female of the species is trying to determine which males carry the best genes to increase her offspring's chance of survival. As I said, choosing a male who survives and thrives despite some absurd impediment such as a giant tail is a marker for a male that is quite hardy, or fit.No, fitness, by definition, is reproductive fitness. The more children one has - the more fit.
