This type of natural selection is called directional selection and does not display a normal curve of expressed traits, but a heavy set of data to the left of the curve that indicates the direction of selection of the extreme phenotype.
Disruptive selection is where two extreme phenotypes are maintained in a population. This curve looks like a two humped camel in it's expression of these extreme traits.

Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
In evolution survival of the fittest refers to?
In evolution, natural selection is often called survival of the fittest.
What are an individual's observable traits called?
genotype or phenotype
Is the struggle between organisms to survive in a habitat with limited resources called the natural selection?
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural 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.
In a population of horses an extreme phenotype is favored and the distribution of genes in that population shifts toward that phenotype This process is called selection?
the process is called an DIRECTIONAL selection.
In a population of horses an extreme phenotype is favored and the distribution of genes in that population shifts toward that phenotype What is the process called?
directional selection
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
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
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce is called?
natural selection
What is the most common name for natural selection?
Natural selection is often (and misleadingly) called 'survival of the fittest'.
In evolution survival of the fittest refers to?
In evolution, natural selection is often called survival of the fittest.
When natural selection favor the intermediate version of a characteristic it is called?
stabilizing selection
Can you have evolution without natural selection?
Of course you can. Google genetic drift and gene flow for two evolutionary drivers ( weak drivers ) that have nothing to do with natural selection. Then there is that subsection of natural selection called sexual selection.
Can natural selection act upon body shape?
Yes, that would be called the Homologous structure, and that changes in natural selection.
What is the name for the process in which the organisms best adapted to their environment surivive?
It's called 'survival of the fittest.' or more scientifically called Natural Selection
What kind of selections occurs in many birds when males that build strong nests help care for young are chosen by females as mates?
This is called, sexual selection.
