Answer: option D) II, III, and IV only
II. Mutations can have a positive effect on an individual.
III. Mutations can have no effect on an individual.
IV. Mutations usually have a negative effect on an individual.
Explanation:
The effects of mutation on the fitness of an organism include:
II) a mutation can be positive once it increases the fitness of the organism e.g the emergence of the malaria-resistant sickle cell hemoglobin gene (AS) instead of the AA gene that is susceptible to malaria attack.
III) a mutation that occurs in an amino acid that results in the use of a different, but chemically similar amino acid e.g a change from AAA to AGA will encode arginine, a chemically similar molecule to the intended lysine. This is called a NEUTRAL MUTATION - and it has no effect on the organism
IV) In general, mutations usually are deleterious - having negative effects - and reducing the fitness of organism. e.g Sickle cell anemia and hemophilia are due to mutations
