A DNA mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes. DNA mutations can affect an offspring can result in abnormal protein products. Mutations can also introduce new alleles into a population of organisms and increase the population's genetic variation.

Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. The fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms.
