Which process can create new alleles?

Mutation:

1. The mutation is the process of producing new alleles of a gene.
2. It's a natural process that alters a DNA sequence and produces alleles, which are slightly different variants of the same gene.
3. Every individual is distinct due to these minor variations in DNA sequence.
4. They explain the differences in human hair colour, skin colour, height, shape, behaviour, and disease susceptibility.
