More … WebSep 24, 2015 · The answer to your headline question is that no, fixation rate is not always equal to the mutation rate for neutral alleles. For instance: Fixation rates for neutral alleles are affected by changes in population size, given a constant mutation rate. In general, fixation rates are lower in growing populations ( Waxman 2012 ).

WebCarbon from carbon dioxide—inorganic carbon—can be incorporated into organic molecules; this process is called carbon fixation, and the carbon in organic molecules is also known as fixed carbon. The carbon that's fixed and incorporated into sugars during photosynthesis can be used to build other types of organic molecules needed by cells.
