Tell me which statement belongs to either natural selection, genetic drift, or gene flow Can you tell me if I am correct? -Consistently causes a population to become better adapted to its environment (I said this is natural selection). -Causes allele frequencies to fluctuate randomly (I said this is genetic drift). -Responsible for the founder effect (I said this is genetic drift). -Cannot cause a harmful allele to become more common (I said this is genetic drift). -Can introduce new alleles into a population's gene pool (I said this is gene flow). -A result of the movement of fertile individuals or their gametes (I said this is gene flow). -A result of differential success in reproduction (I said this is natural selection). -Responsible for the bottleneck effect (I said this is genetic drift).
