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: ...
BIOLOGYPOPULATION geneticsDesigning effective curricula is challenging. Content decisions can impact both learning outcomes and student engagement. As an example consider the place of Hardy-Weinberg equilibria (HWE) and genetic drift calculations in introductory biology courses, as dis...
Genetic drift plays an important role in conservation biology where it is one of the factors that determines the minimal viable population size of a species. Genetic drift is also at the heart of the shifting-balance theory of evolution and of the neutral theory of molecular evolution. 展开 ...

We review how diverse evolutionary mechanisms are treated, both in biology education research and in a sample of high school and college teaching standards. The instruments assess how biology undergraduates understand three evolutionary processes other than natural selection: genetic drift, dominance relatio...
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 ...
