A gene mutation is a change in the nucleotide sequence of a section of DNA coding for a specific trait
Types of Gene Mutations
- New alleles are formed by mutation
- Beneficial mutations change the gene sequence (missense mutations) to create new variations of a trait
- Detrimental mutations truncate the gene sequence (nonsense mutations) to abrogate the normal function of a trait
- Neutral mutations have no effect on the functioning of the specific feature (silent mutations)
