Figure%: The standard distribution of a trait across a population. Stabilizing selection. When selective pressures select against the two extremes of a trait, the population experiences stabilizing selection. For example, plant height might be acted on by stabilizing selection.
Explore how organisms with different traits survive various selection agents within the environment.
Oct 31, 2023 · disruptive selection: (or diversifying selection) a mode of natural selection in which extreme values for a trait are favored over intermediate values. stabilizing selection: a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
May 20, 2023 · Natural selection may affect the distribution of a polygenic trait. These graphs show three ways this can happen. For a review of natural selection and genetic drift, and how they relate to evolution, see http ://www.cultureunplugged.com/play/2533/Mechanisms-of-Evolution .
Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits.
An interactive simulation that explores how different traits in organisms affect their survival within the environment.
Apr 9, 2009 · This paper provides an overview of the basic process of natural selection, discusses the extent and possible causes of misunderstandings of the process, and presents a review of the most common misconceptions that must be corrected before a functional understanding of natural selection and adaptive evolution can be achieved.
