What are the three patterns of of natural selection?
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
Which kind of selection eliminates extreme phenotypes?
disruptive selection
What do stabilizing selection and disruptive selection have in common apex?
They both decrease genetic variation
How are directional and stabilizing selection different?
Directional selection favors individuals at one extreme of a trait distribution, leading to a shift in the population's trait mean over time. In contrast, stabilizing selection favors individuals with intermediate traits, reducing variation and maintaining the status quo by selecting against extremes. While directional selection promotes change in a trait, stabilizing selection promotes stability within a population's traits.
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
Stabilizing selection is the type of natural selection that acts against extreme forms of a polygenic trait to reduce genetic variation and maintains the average value of the trait within a population. It favors the intermediate phenotype, leading to a narrowing of the range of variation for that trait over time.
What is the type of natural selection that favors intermediate phenotypes?
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
What are the three patterns of of natural selection?
The three patterns of natural selection are directional selection, stabilizing selection, and disruptive selection. Directional selection favors individuals at one extreme of a trait distribution, stabilizing selection favors the intermediate phenotype, and disruptive selection favors individuals at both extremes of a trait distribution.
When individuals with an average form of a trait have the highest fitness?
Stabilizing selection
Which kind of selection eliminates extreme phenotypes?
disruptive selection
Which natural selection select against both extremes?
Stabilizing selection.
