The mating preferences of female seaweed flies Coelopa frigida were determined by observing their acceptance or rejection of males of known size. The inversion karyotype of both males and females was also determined. Females exhibited a preference to mate with large males, and evidence is presented that a genetic correlation exists between the female preference and the preferred trait. Females carrying the inversion karyotype associated with large male size showed a strong preference for large males; females carrying the inversion associated with small male size also exhibited a preference for large males, but it was significantly less strong. This finding suggests that a Fisherian process may be operating.
通过观察雌性海藻蝇（Coelopa frigida）对已知大小雄性的接受或拒绝情况，确定了它们的交配偏好。同时也确定了雄性和雌性的倒位核型。雌性表现出与大型雄性交配的偏好，并且有证据表明雌性偏好与偏好性状之间存在遗传相关性。携带与大型雄性大小相关的倒位核型的雌性对大型雄性表现出强烈的偏好；携带与小型雄性大小相关的倒位的雌性也表现出对大型雄性的偏好，但强度明显较弱。这一发现表明可能存在费雪过程。
