What is Mutation?
The DNA sequence varies from creature to organism. The order of the base pairs can occasionally shift. We refer to it as a mutation. Changes in proteins that are translated from the DNA by a mutation are possible.
A abrupt, heritable change in an organism's characteristics is called a mutation. One who demonstrates these heritable changes is referred regarded as a "mutant." Recessive genes are typically produced through mutations.
Genetic differences between animals are brought on by the mutation. Generations after generation inherit advantageous mutations.
For instance, sickle cell anemia results from a mutation in the gene that codes for hemoglobin. The RBCs take on the shape of a sickle. The African population, however, is protected from malaria by this mutation.
