What name is given to a sudden change in a gene or chromosome?
Answer Details
A sudden change in a gene or chromosome is called a "mutation." Mutations are changes in the DNA sequence that can result in altered or new characteristics in an organism. They can occur spontaneously or be induced by external factors such as radiation or chemicals. Mutations can have different effects, ranging from neutral or harmful to beneficial, depending on the location and nature of the change. The occurrence of mutations is the basis of genetic diversity, which is essential for evolution and adaptation of species to changing environments.
