• Inheritance of Acquired Characteristics

• Mutation

Answer explanation

The idea of Inheritance of Acquired Characteristics is not true. Traits that are acquired during an organism's life cannot be inherited by its offspring. In order for a characteristic or trait to be passed down to the next generation, it must be part of the individual's genotype.

Examples of acquired characteristics: large muscles from working out, reading (because it has to be learned), riding a bike (because it has to be learned), an injured body part, etc.

Answer explanation

Random changes in genetic material may result in making different proteins.

• Evolution

• Natural Selection

• Fitness

• Inheritance of Acquired Characteristics

• Mutation

Answer explanation

Mutations cause different proteins to be made by the body. Different proteins build different traits. These mutations can be harmful, beneficial, or neutral.
