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.

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.
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.
The graphs of the 3 types of selection and label the average and the extremes?
In stabilizing selection, the average phenotype is favored, leading to a reduction in extreme phenotypes. In directional selection, one extreme phenotype is favored, causing a shift in the average towards that extreme. In disruptive selection, both extreme phenotypes are favored over the average, leading to a bimodal distribution in the population.
What are the different types of natural selection and how do they impact the evolution of species?
There are three main types of natural selection: directional selection, stabilizing selection, and disruptive selection. Directional selection occurs when one extreme trait is favored over others, leading to a shift in the population towards that trait. Stabilizing selection favors the average trait, reducing genetic variation in a population. Disruptive selection favors extreme traits, leading to the divergence of a population into two distinct groups. These types of natural selection impact evolution by influencing which traits are passed on to future generations. Over time, they can lead to the adaptation of species to their environment and the emergence of new species.
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?

Which of the three types of natural selection works to preserve genetic variability within the population?
stabilizing
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
What are the 4 types of natural selection?
The four types of natural selection are stabilizing selection (where the average phenotype is favored), directional selection (where one extreme phenotype is favored), disruptive selection (where both extreme phenotypes are favored), and sexual selection (where traits that increase mating success are favored).

What is the prefix and suffix of natural selection?
The prefix of natural selection is "natural" and the suffix is "-tion".
