The best method to show that geographic differences in behavior are genetic is to raise the flies from different regions in a common environment. If the behavioral differences persist, then it suggests that the differences are genetic and not solely due to different environmental factors. This method controls for environmental influences and helps isolate genetic factors that contribute to behavioral differences. Sequencing DNA or measuring other behavioral traits may provide additional information, but they do not directly address the question of whether the differences are due to genetic or environmental factors.
