Oww ill correct my spelling
its accidental not aciidental
It depends on what you mean by "accidental." Changes that occur biologically can include things like deletion mutations, translocation, etc. they are mutations but I don't like the term accidental because our bodies have thousands of mutations occurring at all times although most mutations have no effects. However sometimes scientists purposely change DNA through radiation, cross breeding, interbreeding, or gene splicing.
