During what selection the intermediate phenotype is selected for?

When the intermediate phenotype is favored the extreme phenotypes are being selected?

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.

Question Answer
what type of selection occurs when individuals in a population with the intermediate phenotype are selected for disruptive
when a few individuals start a new colony it most likely results in genetic drift through the founder effect

Artificial selection has been used by humans to speed up the process of divergent evolution.
The type of selection that may eliminate intermediate phenotypes is disruptive selection.
The movement of alleles into or out of a population due to migration is called gene flow.

What is selected during natural selection?

What is “selected” during natural selection? Explain your answer. Individuals with certain advantageous traits are selected, in the sense that they produce the most offspring. Different species have traits that increase fitness in a particular environment.

Which type of selection would lead to two distinct phenotypes?

Directional selection favors one extreme; stabilizing selection favors the middle of the range; disruptive selection favors both extremes and leads to two phenotypes.

What occurs when an intermediate phenotype is favored?

Directional selection occurs when one extreme phenotype is favored by natural selection. During stabilizing selection, the intermediate phenotype is favored and becomes more common in the population.

In which type of selection are extreme phenotypes eliminated and the intermediate phenotype is favored?

Diversifying (or disruptive) selection: Diversifying selection occurs when extreme values for a trait are favored over the intermediate values. This type of selection often drives speciation. Diversifying selection can also occur when environmental changes favor individuals on either end of the phenotypic spectrum.

When two or more extreme phenotypes are favored over any intermediate phenotype This is referred to as?

Stabilizing selection. -Occurs when an intermediate phenotype is favored. -Extreme phenotypes selected against. -Individuals near the average are favored. -Most common form of selection bevause the average individual is well adapted to its environment.

Which type of selection favors individuals with intermediate phenotypes and selects against individuals with extreme phenotypes quizlet?

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.

What usually occurs during intersexual selection?

What usually occurs during intersexual selection? … Neither males nor females participate in sexual selection rituals because they are costly to overall survival. A member of one sex usually chooses their mate based on queues that exhibit good genes. Males fight with other males for access to females.

What type of selection sees the phenotype decline if it becomes too common?

In frequency-dependent selection, the fitness of a phenotype declines if it becomes too common in the population.
