A generalization of the concept of the differential of a function of one variable. This function is attributed to SER. In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. In general, mutation is the primary source of genetic variation, which is the raw material for evolution through natural selection. variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
