Indigenous Andean people from Chile and Argentina have been exposed to arsenic over 7 000 years They have a unique genetic mutation in the AS3MT gene which is the coding gene of the Arsenic 3 Methyltransferase enzyme that allows them to metabolize arsenic very well in the liver Indeed geneticists have found the genotype frequency for that mutation is CC 80 and these populations are NOT under Hardy Weinberg equilibrium Which of the following is the main evolutionary force acting in these populations Gene flow Natural selection Genetic drift None of the answers are correct Random mating
