3.32 Types of Mutation

Understand that many mutations are harmful but some are neutral and few are beneficial

Gene ==> New alleles [mutation]
Alleles are responsible for phenotype
New phenotype could be:
- Beneficial e.g. enzyme
- Neutral (neutrality may not last forever - +environmental changes may affect it and turn it beneficial or neutral)
- Harmful e.g. non functional enzyme
