Birth weight in human babies is one good example. Too small and babies lose heat rapidly and are also prone to infectious disease. Too large and they endanger themselves and their mothers by the great difficulty they have passing through the birth canal. So, a small range of birth weights have been selected for and this remains stabilized by the constraints listed above.

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.
When individuals with an average form of a trait have the highest fitness?
Stabilizing selection
Which natural selection select against both extremes?
Stabilizing selection.
Which type of natural selection favors the average individual in a population?
That would be the Stabilizing Selection where there will me not a lot of genetic variation. The curve of the population allele frequency would be quite thin with the extreme being in the middle.
What is the type of selection in which individuals at one end of the distribution curve higher fitness than individuals in the middle of at the other end?
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
Stabilizing selection results in more or less genetic diversity?
Stabilizing selection results in less genetic diversity in a population.
Which kind of selection eliminates extreme phenotypes?
disruptive 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
Which natural selection select against both extremes?
Stabilizing selection.
What is stabilizing selection against?
It is against an extreme phenotypes arising in a population of organisms. Height in humans is under stabilizing selection so that the normally distributed height of humans, save some outliers, describes the standard Bell curve.
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
