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?
directional selection
How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
How do you use natural selection and evolution in a sentence?
didn't you just do that? or did you mean something else? ... Or........... Over time, the change in a species is called evolution. and. Natural selection helps certain animals in a species survive.
What is a beneficial feature that evolved by means of natural selection?
Your brain is one of the most important human features evolved by natural selection. ( perhaps sexual selection also had something to do with it )
Tends to favor phenotypes at one extreme of the range of variation?
DIRECTIONAL Selection
What selection favors organisms with phenotypes that are at one extreme rlative to the average phenotype?
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
Selection favors one extreme form of a trait in a population.?
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
What kind of natural Selection would eliminate one extreme?
Directional selection
What is direct selection?
Directional selection is when natural selection favors a single phenotype. It occurs when there is a shift in population towards an extreme version of a beneficial trait.
What natural selection called at extreme phenotype?
This type of natural selection is called directional selection and does not display a normal curve of expressed traits, but a heavy set of data to the left of the curve that indicates the direction of selection of the extreme phenotype.Disruptive selection is where two extreme phenotypes are maintained in a population. This curve looks like a two humped camel in it's expression of these extreme traits.
How does natural selection favor an organism's heritable trait?
Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.
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?
directional selection
What is the relationship between evolution and natural selection?
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
What is a selection that eliminates individuals on both ends of the range and favors those in the middle?
One standard deviation.
How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
What are the 3 ways natural selection can affect a population?
Directional selection: favors the phenotype at one extreme of a trait's range, selecting against the opposite extreme.Stabilizing selection: favors the intermediate phenotype, selecting against the phenotypes at both extremes of the trait's range.Disruptive selection: favors phenotypes at both extremes, selecting against the intermediate phenotype of the trait's range.
What is the selective agent in natural selection?
They are the selective agent in natural selection ;)
