genetic) isolation between them, then the significance of any ethological isolation observed is equivocal since they are already genetically isolated lineages.
A one-way bias in ethological isolation, where barriers to pollen flow between the two species are not symmetrical, has also been observed in the relationship between Bombus and Rhinanthus (Kwak, 1978).

Changes in mating behavior produced by selection for ethological isolation between ebony and vestigial mutants of Drosophila melanogaster.
Selection for and against ethological isolation between Drosophila pseudoobscura and Drosophila persimilis.
Hawaiian Drosophila are a favorable subject for studies on the genetic mechanisms underlying ethological isolation
(Carson 1978; Kaneshiro 1989).
However, significant ethological isolation between individual populations is observed in only a few of the very many cases tested, although in a few more than is expected by chance; and, with one exception, ethological isolation between particular populations does not persist through the various cycles.
If this were correct, ethological isolation would be also expected between inbred populations, such as the "prima" (F > 0.
