{{Short description|Frequency of mutation of genes}} '''Mutation frequency''' and mutation rates are highly correlated to each other. Tests for mutation frequency are cost effective in laboratories <ref>Araten, D., Golde, D., Zhang, R., Taler, H., Gargiulo, L., Notaro, G., & Luzzatto, L. (2005). A quantitative measurement for the human somatic mutation rate. Cancer Research, (65), 8111-8117.</ref> however; these two concepts provide vital information in reference to accounting for the emergence of mutations on any given germ line.<ref>Peruzzi, B., Araten, D., Notaro, R., & Luzzatto, L.

The use of pig-a as a sentinel gene for the study of the somatic mutation rate and the mutagenic agents in vivo.

There are several tests utilized in measuring the chances of mutation frequency and rates occurring in a particular gene pool. Some of the test are as follows: * Avida Digital Evolution Platform <ref>Clune, J., Misevic, D., Ofria, C., Lenski, R., Elena, S. F., & Sanjuan, R. (2008). Natural selection fails to optimize mutation rates for long-term adaptation on rugged fitness landscapes.

Mutation frequency and rate provide information about how often a mutation may be expressed in a particular genetic group or sex.<ref>Yoon, S., Qin, J., Glaser, R., Jabs, E., Wexler, N., Sokol, R., Arnheim, N., & Calabrese, P. (2009). The ups and downs of mutation frequencies during aging can account for the apert syndrome paternal age effect. PLos Genetics, 5(7), 1-19.</ref> For example, Yoon et al. (2009), suggested that there were higher sperm mutation frequencies in sperm from older donors. This suggests that males can contribute to genetic disorders of X-linked recessive chromosomes.<ref>http://users.rcn.com./jkimball.ma.ultranet/BiologyPages/M/Mutations.html(http://users.rcn.com./jkimball.ma.ultranet/BiologyPages/M/Mutations.html) {{Dead link|date=February 2022}}</ref> Evolutionary influences affect mutation frequency and rate. Analyzing the mutation frequency and rates of a particular species may provide a way to understand the genetic component of its longevity <ref name="Nishant, K. 2009"/>
==Aging==
The time course of spontaneous mutation frequency from middle to late adulthood was measured in four different tissues of the mouse.<ref name = Hill2005>Hill KA, Halangoda A, Heinmoeller PW, Gonzalez K, Chitaphan C, Longmate J, Scaringe WA, Wang JC, Sommer SS. Tissue-specific time courses of spontaneous mutation frequency and deviations in mutation pattern are observed in middle to late adulthood in Big Blue mice. Environ Mol Mutagen. 2005 Jun;45(5):442-54. doi: 10.1002/em.20119. PMID 15690342</ref> Mutation frequencies in the cerebellum (90% neurons) and male germ cells were lower than in liver and adipose tissue. Furthermore, the mutation frequencies increased with age in liver and adipose tissue, whereas in the cerebellum and male germ cells the mutation frequency remained constant<ref name = Hill2005/>
Dietary restricted rodents live longer and are generally healthier than their ad libitum fed counterparts. No changes were observed in the spontaneous chromosomal mutation frequency of dietary restricted mice (aged 6 and 12 months) compared to ad libitum fed control mice.<ref>Stuart GR, Oda Y, Boer JG, Glickman BW. No change in spontaneous mutation frequency or specificity in dietary restricted mice. Carcinogenesis. 2000 Feb;21(2):317-9. doi: 10.1093/carcin/21.2.317. PMID 10657975</ref> Thus dietary restriction appears to have no appreciable effect on spontaneous mutation in chromosomal DNA, and the increased longevity of dietary restricted mice apparently is not attributable to reduced chromosomal mutation frequency.
