WebIn genetics, the mutation rate is the frequency of new mutations in a single gene or organism over time. ... Whereas the spectrum of de novo mutation rates reflects mutagenesis alone, this kind of spectrum may also reflect effects of selection and ascertainment biases (e.g., both kinds of spectrum are used in ).
