Fixation can refer to a gene in general or particular nucleotide position in the DNA chain . In the process of substitution , a previously non-existent allele arises by mutation and undergoes fixation by spreading through the population by random genetic drift or positive selection . 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 Additionally, research has been done into the average time it takes for a neutral mutation to become fixed. Kimura and Ohta (1969) showed that a new mutation that eventually fixes … See more • Gillespie, J.H. (1994) The Causes of Molecular Evolution. Oxford University Press. • Hartl, D.L. and Clark, A.G. (2006) Principles of … See more The earliest mention of gene fixation in published works was found in Motoo Kimura's 1962 paper "On Probability of Fixation of Mutant … See more Under conditions of genetic drift alone, every finite set of genes or alleles has a "coalescent point" at which all descendants … See more In 1969, Schwartz at Indiana University was able to artificially induce gene fixation into maize, by subjecting samples to suboptimal conditions. Schwartz located a mutation in a gene … See more WebOct 3, 2008 · A general link between gene activity and radial position is even more strongly challenged by observations on single genes.
