Definition
Glossary of "Life (9th ed.)" by Sadava et al. (2011)
- Changes in gene frequencies from generation to generation as a result random (chance) processes.
Glossary of "Plant Systematics (1st ed.)" by Simpson (2006)
- Random genetic modification of a population or species, not the result of natural selection.
Glossary of "Evolution of Plants (2nd ed.)" by Willis & McElwain (2014)
- The random fluctuations of gene frequenceis in a population such that the genes of offspring are not a perfectly representative sampling of the parental genes.
Glossary of "Evolution (4th ed.)" by Futuyma & Kirkpatrick (2017)
- Random changes in the frequencies of two or more alleles or genotypes within a population.
Glossary of "Ancestors in Our Genome" by Harris (2015)
- random changes in the frequency of a DNA variant or allele in a population (i.e., how common it is in the population or species) as a result of random variation in individual reproduction.
Glossary of "Environmental Science: Earth as a Living Planet (2nd ed.)" by Botkin & Keller (1998)
- Changes in the frequency of a gene in a population as a result of chance rather than of mutation, selection, or migration.
