I find two closely related species of fly, one (P) of which appears to reproduce parthenogenetically while the other (S) reproduces sexually. In the same location, I find a bizarre third kind of insect, a sterile defensive form with enlarged mandibles. Because it is sterile, I conclude that this form must be produced by either P or S. Which do you think is most likely the producer of the sterile defensive individuals? Explain your answer.
