Design an experiment to determine whether lactase persistence in the different global hot spots was caused by one or several mutations

Collect DNA from individuals who are lactase persistent and are from the global hot spot populations. Then look for genetic differences correlated with lactase persistence; the first place to look would be in and around the lactase gene. Compare the genetic differences to see if they are the same or different.
