occurs when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle. Disruptive selection acts against individuals of an intermediate type and can create two distinct phenotypes.The answer is disruptive selection. In disruptive selection two opposite extremes of a trait are favoured by nature while average trait is gradually eliminated resulting in an increase in diversity.Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.
Which type of selection leads to 2 different populations?
The answer is disruptive selection. In disruptive selection two opposite extremes of a trait are favoured by nature while average trait is gradually eliminated resulting in an increase in diversity.
Which type of selection occurs when 2 extreme phenotypes are advantageous?
Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.

Which process would most likely favor the phenotype that is currently the most common phenotype?
During stabilizing selection, the intermediate phenotype is favored and becomes more common in the population. Disruptive selection occurs when both extreme phenotypes are favored, while individuals with intermediate phenotypes are selected against by something in nature.
How do stabilizing and disruptive selection differ?
Disruptive selection is a mode of natural selection which favours extreme values over intermediate values in a population. Stabilizing selection is a mode of natural selection which favours an average trait value over two extreme trait values.
Which type of selection can result in the formation of two new species?
Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.
What is the difference between directional and stabilizing selection?
Stabilizing selection (left column) acts against phenotypes at both extremes of the distribution, favouring the multiplication of intermediate phenotypes. Directional selection (centre column) acts against only one extreme of phenotypes, causing a shift in distribution toward the other extreme.
What is the difference between disruptive selection and directional selection?
The main difference between directional and disruptive selection is that directional selection favors a phenotype most fitted to the environment whereas disruptive selection favors extreme values for a trait over intermediate values.

Natural selection in populations (article) | Khan Academy
Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.
Adaptive Evolution – Biology 2e – BC Open Textbooks
Sometimes two or more distinct phenotypes can each have their advantages for natural selection, while the intermediate phenotypes are, on average, less fit.
Adaptive Evolution | BIO 101 General Biology I
Sometimes two or more distinct phenotypes can each have their advantages and be selected for by natural selection, while the intermediate phenotypes are, …
Evolution II – Estrella Mountain Community College
Disruptive selection favors individuals at both extremes of variation: selection is against the middle of the curve. This causes a discontinuity of the …
What is stabilizing selection example?
Stabilizing Selection When selective pressures select against the two extremes of a trait, the population experiences stabilizing selection. For example, plant height might be acted on by stabilizing selection. A plant that is too short may not be able to compete with other plants for sunlight.
Does natural selection act on phenotypes?
Natural selection acts on phenotypes, yet evolution occurs at the level of genotypes. Accordingly, the more direct the links are between phenotypes and genotypes, the more effectively natural selection can shape genetic variation and drive adaptation.
What do stabilizing selection and directional selection have in common?
Stabilizing and directional selection both drive homogeneity in a specific trait, reducing diversity.

What is directional selection?
Directional selection occurs when individuals with traits on one side of the mean in their population survive better or reproduce more than those on the other. It has been demonstrated many times in natural populations, using both observational and experimental approaches.
What is directional selection example?
An example of directional selection is giraffe neck lengths. The environment created a selection pressure which favored giraffes with longer necks who could reach more food in the trees. At the same time, there was selection pressure against giraffes with shorter necks.
What is divergent natural selection?
Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation.
What is the difference between artificial selection and natural selection?
Artificial selection is distinct from natural selection in that it describes selection applied by humans in order to produce genetic change. When artificial selection is imposed, the trait or traits being selected are known, whereas with natural selection they have to be inferred.
Which type of selection is most likely to create new species?
Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
What causes stabilizing selection?
Simply stated, there is no common cause of stabilizing selection, besides the fact that the most average individual is selected for. In that way, like all forms of selection, the cause of stabilizing selection is the increased fitness and reproductive success that the median individuals have.
How can disruptive selection lead to a new species?
Disruptive selection is an evolutionary force that drives a population apart. The disruptive selection will cause organsisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more. This causes the alleles for the extreme traits to increase in frequency.
What is destructive selection?
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.

What happens during stabilizing selection?
The stabilizing process is one that results statistically in an over-represented norm. In other words, this happens when the selection process—in which certain members of a species survive to reproduce while others do not—winnows out all the behavioral or physical choices down to a single set.
How can natural selection favor different phenotypes at different times?
Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection, …
