Because they create multiple alleles, mutations can cause D.variations in traits.
<h2>Gene mutations and evolution</h2>
The production of mutations in DNA molecules is known as mutagenesis. Changes in DNA sequence or chromosome rearrangement are just two examples of mutations that can occur in DNA. These mutations can happen on their own, as a result of mistakes made during DNA replication or mitosis. Natural selection requires genetic variety, which is produced by spontaneous mutations.
The process by which populations of organisms change over generations is known as evolution. These modifications are caused by genetic differences. Different features in an organism can be introduced by genetic differences that modify gene activity or protein function. If a characteristic is beneficial and helps an individual survive and reproduce, it is more likely to be handed down to the following generation (a process known as natural selection).
