WebThe Fisherian mechanism is, in essence, based only on genes that inßuence mating preferences and preferred traits, and it can lead to their rapid coevolution if the most preferred males are polygynous (e.g. [2,5,10,17] ). Genetic indicator mechanisms, however ,depend on overall quality and hence on much or most of the functional genome; they http://www.columbia.edu/~mu2166/neoFisher/fisher.pdf
