You have sampled height from two populations: the Maasai of East Africa and the Inuits of Alaska. You have determined that there is a significant difference in height between these two populations, with Inuits being of shorter height than the Maasai. Can you argue that this variation that you observe due solely to genetics? Why or why not? How would you test the hypothesis that stature in each of these two groups is genetic?
