MUTATIONS
... Mutations are the source of the altered versions of genes that provide the raw material for evolution. Most mutations have no effect on the organism, especially among the eukaryotes, because a large portion of the DNA is not in genes and thus does not affect the organism’s phenotype. Only a sm ...
