A) This mutation was dominant. For this reason, over generations, the allele became more and more frequent. B) This mutation gave a reproductive advantage to people who carried it in the environments of Europe. So, over generations, the allele became more and more frequent until it predominated in this population. C) A mutation must have occurred in the population ancestral to modern Europeans after their migration to Europe. D) A mutation must have occurred in the population ancestral to modern Europeans before their migration to Europe. E) A mutation must have occurred in the population ancestral to modern Europeans either before or after their migration to Europe. F) The same mutations have occurred very often, so the allele became more and more frequent until it predominated in this population. aits ple notica Studi port prot ght-colored fi inding that the pigmentExplanation / Answer
