Genetic mutation, a change in the DNA sequence that creates variation among organisms, can be referred to by a number of synonyms. One common term used is "genetic variation," which implies a range of diversity in the genetic material of an individual or population. Another is "genetic alteration," which highlights the modification of genetic code. Other synonyms include "mutagenesis," "gene modification," "genetic change," and "genetic transformation." Regardless of the term used, genetic mutations can lead to changes in traits or characteristics, and play a crucial role in the evolution of species. They can occur spontaneously or as a result of environmental factors such as radiation or chemicals.
