“…The experimental support for female choice being inherited is more limited. Only in the two-spot ladybird beetle, Adalia bipunctata, does direct evidence exist for a polymorphism with a genetic basis (Majerus et a!., 1982(Majerus et a!., , 1986O'Donald and Majerus, 1985;Majerus, 1986), although convincing indirect evidence has been obtained in Drosophila melanogaster (Heisler, 1984) and the Trinidad guppy, Poecilia reticulata (Breden and Stoner, 1987). We report here an association in seaweed flies between mating success, female choice and the possession of a particular allele at an enzyme-determining locus.…”
