Mutations are sudden changes that may occur in a gene or chromosome. These changes may affect the way traits are inherited. If a mutation occurs in a body cell, such as a bone cell, the mutation affects only the organism that has it. If the mutation occurs in a sex cell, then it can be passed on to an offspring. Some mutations are helpful and can be desirable in an offspring. Determine whether each item below is part of the human life cycle, the cell cycle, or both.
