What are the three patterns of of natural selection?
directional selection,stabilizing selection, anddisruptiveselection
Which kind of selection eliminates extreme phenotypes?
disruptive selection
What do stabilizing selection and disruptive selection have in common apex?
They both decrease genetic variation
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
directional selection
Selection occurs when the environment continually eliminates extremes at both ends of a range of phenotypes?
Stabilizing selection.
What is the type of natural selection that favors intermediate phenotypes?
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
What are the three patterns of of natural selection?
directional selection,stabilizing selection, anddisruptiveselection
When stabilizing selection acts to elimination extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase?
That is the definition of stabilizing selection.
When individuals with an average form of a trait have the highest fitness?
Stabilizing selection
Which kind of selection eliminates extreme phenotypes?
disruptive selection
Which natural selection select against both extremes?
Stabilizing selection.
A population of mice lives near a stream The larger mice tend to live longer and over many generations the average mouse size gets larger What type of selection is this?
Directional selection
The curve on the left shows the height of a population of penguins. The curve on the right shows the population five years later. What has happened to this population?
Directional Selection - APEX
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection results in less genetic diversity in a population.
What modes of selection leads to a reduction in variation but no change in the mean?
Stabilizing selection.
When natural selection favor the intermediate version of a characteristic it is called?
stabilizing selection
What do stabilizing selection directional selection have in common?
They both decrease genetic variation .
