RATES OF MUTATION Mutation rates are typically scored by the frequency with
which a new mutant arises among the progeny in a population ( often a
laboratory population ) of nonmutant individuals . Hence they are expressed as

The genetic background in which a mutation arises often determines its fate . The
simplest instance is that of a genetic priority effect : a new , possibly beneficial
mutation is not advantageous if its function is already served by an established ...

Moreover , even if an individually disadvantageous trait is temporarily fixed in a
population by group selection , the genetic constitution is unstable , because if an
individually advantageous allele again arises by mutation ( or enters by gene ...
