Final answer:
A lethal mutation is the type of mutation that is most rapidly lost from a population since it significantly decreases an organism's fitness and often leads to death before reproduction, preventing the mutation's transmission to future generations.
Step-by-step explanation:
Of the options presented, the type of mutation that will generally be lost from the population most rapidly is a lethal mutation. Lethal mutations are those that drastically lower an organism's fitness, often leading to death before the organism can reproduce. This means these mutations will quickly be eliminated from the gene pool as the organisms carrying them do not live long enough to pass the mutations on to their offspring.
Beneficial mutations, by contrast, increase an organism's fitness and are likely to be passed on to subsequent generations. Neutral mutations, including most silent mutations, do not affect an organism's ability to survive and reproduce, and thus they may remain in the population without being subject to natural selection. Silent mutations are a subset of neutral mutations, which do not alter the amino acid sequence of proteins, often having no impact on fitness.
