3.32 Types of mutation

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

We start of with the original copy of the gene. Mutation then produces new alleles which are responsible for the phenotype. Their impact could be either beneficial, harmful or neutral and have no positive of negative effect.

Beneficial mutation: To improve the efficiency of an enzyme.

Harmful Mutation: Leads to the production of an enzyme that doesn’t work.

Neutral Mutation: leads to a second or new alleles which has no affect. However this may not last forever, and this new or second alleles could become beneficial or harmful when we have environmental change.
