Biology definition: Genetic drift is the drifting of the frequency of an allele relative to that of the other alleles in a population over time as a result of a chance or random event. An example where the effect of genetic drift is magnified is the so-called bottleneck effect. Synonyms: ...
Explore genetic drift. Learn the definition of genetic drift and understand its types. Discover the importance of genetic drift in evolution with...
Examples of Genetic Drift To exemplify the genetic drift, let’s take a hypothetical example of a population of 100 rabbits that live in the woods. All the rabbits in the woods have various colours of their coats. The colours are black, grey, white, tan, brown and red. In the population...
Twitter Google Share on Facebook genetic drift Thesaurus Medical Encyclopedia Wikipedia Related to genetic drift:gene flow n. Variation in gene frequencies in a population due to chance rather than natural selection, mutation, or immigration.
large populations may have been subjected to genetic drift through bottleneck or founder effects. Genetic drift plays an important role in conservation biology where it is one of the factors that determines the minimal viablepopulation sizeof a species. Genetic drift is also at the heart of the ...
Genetic drift is defined as the changing of the number of available alleles in a population by chance events. Also called allelic drift, this phenomenon is usually due to a very small gene pool or population size. Unlike natural selection, it is a random, chance event that causes genetic dri...
This study explores biology undergraduates' misconceptions about genetic drift. We use qualitative and quantitative methods to describe students' definitions, identify common misconceptions, and examine differences before and after instruction on genetic drift. We identify and describe five overarching categorie...

Genetic drift is one of several forces that make up evolution. This lesson will provide activities and games for your class as you teach them about genetic drift. What Is Genetic Drift? Evolution is a long process, and there are many different factors that affect how organisms change over ...
