What is the type of selection in which individuals of average size?
The type of selection in which individuals of average size have greater fitness than small or large individuals is called a. disruptive selection.
What are the types of selection?
There are several ways selection can affect population variation:
- stabilizing selection.
- directional selection.
- diversifying selection.
- frequency-dependent selection.
- sexual selection.
What type of selection occurs when individuals in a population?

| 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 |
Which type of selection occurs when individuals at one end of the curve have higher fitness than individuals in the middle or at the other end of the curve?
directional selection
When individuals at one end of the curve have higher fitness than individuals in the middle or at the other end, directional selection takes place. The range of phenotypes shifts as some individuals survive and reproduce while others do not. In this case, birds with larger beaks have higher fitness.
What are the three types of selection?
The 3 Types of Natural Selection
- Stabilizing Selection.
- Directional Selection.
- Disruptive Selection.
What is an example of selection?
The definition of a selection is a person or thing that’s been picked or are available to pick. An example of a selection is a cat chosen from a litter of kittens. An example of a selection is a litter of kittens to choose from at the humane society. The act of selecting something.
What are three ways natural selection can affect a population?
Natural selection on polygenic traits can affect the distributions of phenotypes in three ways: directional selection, stabilizing selection, or disruptive selection.
What Animals use Intrasexual selection?
Intrasexual selection deals with members of the same sex in a given species. An example of this can be seen in elephant seals, polar bears, or any other animal that fights a same sex individual for mating, food, or territorial purposes.
Which is an example of a type of selection?
Over time, the woolybeast population consists of individuals with extremely long snouts. This is an example of: A. stabilizing selection B. directional selection C. disruptional selection A. stabilizing selection Before a drought, medium size beaks were most common in the bird population.
Which is the best description of directional selection?
Directional selection. Directional selectionDirectional Selection: A type of selection that removes individuals from one end of a phenotypic distribution and thus causes a shift in the distribution. occurs when natural selection favors one extreme of continuous variation.
Which is the first type of natural selection?
Azcolvin429 (Selection_Types_Chart.png) / [GFDL] The first type of natural selection is called directional selection. It derives its name from the shape of the approximate bell curve that is produced when all individuals’ traits are plotted.
Which is the best description of disruptive selection?
Disruptive or Diversifying selection. Disruptive selectionDisruptive Selection: A type of selection that removes individuals from the center of a phenotypic distribution and thus causes the distribution to become bimodal. occurs when natural selection favors both extremes of continuous variation.
