Difference Between Stabilizing and Balancing Selection

Difference Between Stabilizing and Balancing Selection

The key difference between stabilizing and balancing selection is that stabilizing selection is a type of natural selection which favours average phenotypes in a population while balancing selection is the maintenance of multiple alleles of a gene within a population in order to enhance genetic diversity.

What is an example of balancing selection?

A well-studied case is that of sickle cell anemia in humans, a hereditary disease that damages red blood cells. ... This is an example of balancing selection between the fierce selection against homozygous sickle-cell sufferers, and the selection against the standard HgbA homozygotes by malaria.

What is an example of stabilizing selection?

Stabilizing selection in evolution is a type of natural selection that favors the average individuals in a population. ... Classic examples of traits that resulted from stabilizing selection include human birth weight, number of offspring, camouflage coat color, and cactus spine density.

What is the difference between the three types of selection?

1: 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 ...

Does balancing selection increase genetic variation?

A third regime, balancing selection, is related to diversity and differentiation in more complex ways. By definition balancing selection encompasses all selective regimes that result in increased genetic diversity relative to neutral expectations.

What are the 4 types of selection?

Stabilizing selection, directional selection, diversifying selection, frequency -dependent selection, and sexual selection all contribute to the way natural selection can affect variation within a population.

What are the three types of natural selection?

The 3 Types of Natural Selection

What happens during stabilizing selection?

Stabilizing selection (not to be confused with negative or purifying selection) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. ... This means that most common phenotype in the population is selected for and continues to dominate in future generations.

What are examples of disruptive selection?

Disruptive Selection Examples: Color

What is a common cause of stabilizing selection?

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. The extreme versions or traits have a disadvantage, in one way or another. This disadvantage, in evolutionary terms, is decreased reproduction.

What are the 3 types of evolution?

shows the three main types of evolution: divergent, convergent, and parallel evolution.

Is natural selection random?

The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment.

What are the five principles of natural selection?
