- Quantifying mating preferences is essential to understand how sexual selection shapes both mating systems and sexual dimorphisms. We present a new method for detecting and quantifying both stabilizing and directional mating preferences and demonstrate the experimental and statistical advantages of this method over previous approaches. We illustrate the method using data from a mate choice experiment in which female sand crickets were provided a choice of 2 males. Both directional and stabilizing preference are identified for components of the male call song.
