a mutation causes a specific variation within the population

Answer 1

a mutation causes a specific advantage within the population

Reason: natural selection acts when a genetic change affects an organism's fitness. A mutation that provides a specific advantage will change reproductive success and therefore be subject to selection; reactivation, inactivation, or neutral variation may or may not affect fitness.
