• missense mutation

• nonsense mutation

• frameshift mutation

• point mutation

Why are insertion and deletion mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.

• Monohybrid Trait

• Mutation

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• changes in genotype, but not phenotype
