IB Biology Topic D1.3.7 Mutation as a Source of Genetic Variation Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

Mutation Is The Original Source Of Genetic Variation

Mutations alter the DNA sequence, creating new alleles.
New alleles introduce variation within a population.
Without mutation, all individuals would be genetically identical, leaving nothing for natural selection to act on.

Definition

Mutation

A mutation is a change in the DNA sequence, which can alter the instructions for building proteins or regulating cellular processes.

New Alleles Are Raw Material For Evolution

Mutation supplies the variation, and the environment then decides which alleles spread.
A new allele that improves survival or reproduction becomes more common over generations.
