Nothobranchius furzeri as an emerging model for mate choice: female choice revealed by animations

What is it about?

Using computer animations, we investigate the behavioral response of African turquoise killifish females to males that vary with respect to tail color. These fish provide a promising model for studying the genetic basis of preferences because they are sexually dimorphic, male coloration varies, and genomic tools are available. We demonstrate that females respond to computer animations and exhibit strong preferences based on male coloration, adding another tool for understanding the genetic basis of mating preferences.
