Description:
The mutation component, M, is a measure of the proportion of the impact of a genetic condition that is attributable to recurrent mutation. For a trait maintained by balance between mutation and directional selection, M is approximately the broad-sense heritability; for a measured character where the mean and optimum coincide, M is about half the heritability. If the narrow-sense heritability is high, the impact changes relatively rapidly with a change in mutation rate. If the narrow-sense heritability is low, M cannot be predicted, but the change in impact following a change in mutation rate, if any, is very slow.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Crow, J F -- Denniston, C -- New York, N.Y. -- Science. 1981 May 22;212(4497):888-93.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7233180" target="_blank"〉PubMed〈/a〉
