Description:
In asexual populations, beneficial mutations that occur in different lineages compete with one another. This phenomenon, known as clonal interference, ensures that those beneficial mutations that do achieve fixation are of large effect. Clonal interference also increases the time between fixations, thereby slowing the adaptation of asexual populations. The effects of clonal interference were measured in the asexual RNA virus vesicular stomatitis virus; rates and average effects of beneficial mutations were quantified.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miralles, R -- Gerrish, P J -- Moya, A -- Elena, S F -- New York, N.Y. -- Science. 1999 Sep 10;285(5434):1745-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Cavanilles de Biodiversitat i Biologia Evolutiva and Departament de Genetica, Universitat de Valencia, Apartado 22085, 46071 Valencia, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10481012" target="_blank"〉PubMed〈/a〉
