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 ...

MUTATIONS IN FINITE POPULATIONS In a very large population , the rate of
gene frequency change due to mutation alone is likely to be low , because the
mutation rate at a locus is likely to be about u = 10° or 10 - per gamete per
generation ...
