Stabilizing Selection-- The extremes are selected against.Example: height; mostly beings tend to the average height- not too many really short ones or really tall ones.Directional selection-- One extreme value is selected for.Example: speed; faster is always better so a population will tend to get faster over time.Disruptive selection-- The extremes are both selected for.This type of selection is not as common as the first two. Example: Prey-type animal with distinctive markings which the predators know will over time move away from the norm in both directions.

3. Stabilizing selection
If you need to know more about them then just research. Trust me, it's easier to look it up than it is to ask the question.

∙ 13y ago1. Directional selection (1 extreme phenotype is fittest, and the others are selected against)
2. Disruptive selection (2 [extreme] phenotypes are fitter than the intermediate type and the intermediate is selected against)
3. Stabilizing selection (extreme phenotypes are less fit than optimal (or intermediate) phenotype, and extreme phenotypes are selected against)

What do the three types of natural selection have in common?
The common factor in the three types are that dominant traits are preferred.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What is the selective agent in natural selection?
They are the selective agent in natural selection ;)
Is natural selection a process or a result of a process?
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
The graphs of the 3 types of selection and label the average and the extremes?
There are three types of selections. The three types of selections include: disruptive selection, natural selection, and directional selection.
What is the effect of climate on the size of the finch's beak an example of?
Natural Selection. Bedi<3;)
What are the main types of forces?
motion and natural selection and genetic drift.
What 3 types of Selection pressures that affect a population structure?
The 3 types of selection pressure on a population: 1) "Stabilizing selection" = intermediate phenotypes are favored and extremes on both ends are eliminated. 2)"Directional selection" = is a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. 3) "Disruptive selection/ Diversifying selection" = describes changes in population genetics in which extreme values for a trait are favored over intermediate values
What do the three types of natural selection have in common?
The common factor in the three types are that dominant traits are preferred.
What process produced the two different types of beaks shown?
natural selection
What is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
What are the release dates for Un-Natural Selection - 2011 Cooking with Gas 1-3?

What where the 3 steps that lead to the formation to new species according to the theory of natural selection?
Generally and simply, mutation, genetic variation and natural selection.
Which of the three types of natural selection works to preserve genetic variability within the population?
stabilizing
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
