What else can I help you with?
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 Stabilizing Selection and Distruptive selection?
Stabilizing selection is a type of natural selection that favors the intermediate phenotypes in a population, leading to a decrease in genetic diversity. Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, resulting in increased genetic variation within a population.
What is disputive selection?
Disruptive selection is a type of natural selection that favors extreme traits over the average trait, leading to the divergence of characteristics within a population. This process can result in the formation of two distinct phenotypic groups with reduced variation between them.
What are variation traits?
Variation traits are characteristics that can differ among individuals of the same species, such as height, eye color, or blood type. These traits are influenced by genetics and environmental factors, contributing to the diversity seen within a population. Variation traits play a key role in evolution by providing the raw material for natural selection to act upon.
Does stabilizing selection favors average individuals?
Yes, stabilizing selection favors average individuals by selecting against extreme phenotypes and maintaining the status quo. It arises when individuals with intermediate traits have a higher fitness compared to those with extreme traits, leading to a reduction in genetic variation over time.
Which type of selection in which humans select the variations?
This type of selection is called artificial selection.
Which type of selection tends to increase genetic variation?
Natural Selection.
How do you save a selection in photoshop?
Go to the Select menu, then select Save Selection. Then type in a name for the selection and click OK.
What modes of selection leads to a reduction in variation but no change in the mean?
Stabilizing selection is the mode of selection that can lead to a reduction in variation without changing the mean of a trait. In this type of selection, extreme phenotypes are selected against, while intermediate phenotypes are favored, resulting in a narrower range of phenotypic variation but maintaining the same mean.
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.
When human change the physical characteristics of organism's what type of selection is it?
Breeding.
What type of select did the development by scientists of a new color in a rose is the result from?
Selective breeding, which is a form of artificial selection.
How do you get scene selection for a Cinderella story once upon a song?

The idea that organisms with a particular genotype will have better reproductive success than organisms with a different genotype is called?
Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
What is Stabilizing Selection and Distruptive selection?
Stabilizing selection is a type of natural selection that favors the intermediate phenotypes in a population, leading to a decrease in genetic diversity. Disruptive selection, on the other hand, favors extreme phenotypes over intermediate ones, resulting in increased genetic variation within a population.
What are some of the main reasons for the great variation in even the same type of human - built structure?
its the enviorment
What type of gene flow allows reduction of variation?
Gene flow that involves the movement of individuals from a high-variation population into a low-variation population can result in a reduction of genetic variation. This can happen if the incoming individuals do not introduce new alleles or if genetic drift and selection reduce the frequency of existing alleles.
