Question

How do mutations lead to genetic variation?

Answer 1

Answer:
Genetic variation is based on three primary sources.
1. Mutation
2. Gene flow
3. Sexual reproduction.
Mutation is the change in DNA sequence. Single mutation has effect, but many mutations are responsible for genetic variation. Sickle cell anemia is an example of mutation.

Answer 2

Mutation can be defined as the change in the sequence of DNA. This can be cause to several factors such as physical or chemical mutagens.

Mutation can lead to the create entirely new allele in a population. Random fertilization or recombination that takes place between homologous chromosomes during the process known as meiosis also leads to mutation.

This is how mutations can lead to genetic variation.
