Refer to the figure.
Wilkinson & Reillo (1994) carried out an artificial selection experiment using the stalk-eyed fly Cyrtodiopsis dalmanni. The females from control, long-selected, or short-selected populations chose between a long- or short-stalked male. After 13 generations, eyestalk length was significantly different among the groups. Based on this background and the figure, which of the following statements is false?
A) Females from the long eyestalk-selected population showed a preference for male eyestalk lengths significantly longer than females from the control population did.
B) Females from the short eyestalk-selected population showed a preference for male eyestalk lengths significantly shorter than females from the control population did.
C) This experiment showed that selection for a change in a male trait in a population can indirectly select for a corresponding change in average female preference in the population.
D) Results from this experiment provide support for the "sexy son hypothesis."
