Summary Introduction
Concept introduction: Mutations are heritable changes caused due to a change in a single base pairing or due to chromosomal abnormality. Mutations are the result of unintentional variations in the DNA, which results in lasting modification of the genome of an organism. The effect of mutation is not always morphologically expressed.
