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 ). WebPGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3. In the two other known pathways, C 4 and CAM (crassulacean acid metabolism), the …

Fixation rates can easily be modeled as well to see how long it takes for a gene to become fixed with varying population sizes and generations. For example, at The Biology Project Genetic Drift Simulation you can model genetic drift and see how quickly the gene for worm color goes to fixation in terms of … See more In population genetics, fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains. … See more Under conditions of genetic drift alone, every finite set of genes or alleles has a "coalescent point" at which all descendants converge to a single ancestor (i.e. they 'coalesce'). This fact can be used to derive the rate of gene fixation of a neutral … See more • Gillespie, J.H. (1994) The Causes of Molecular Evolution. Oxford University Press. • Hartl, D.L. and Clark, A.G.
