Is industrial melanism is stabilizing selection?
No, that would be more of a directional selection. Phenotypic change from a minor variant phenotype, black in this case, to the majority phenotype due to the environmental selection pressure of pollution on the moth phenotype.
What type of selection that may eliminate intermediate phenotype is?
disruptive selection
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.
Does stabilizing selection favors average individuals?
Yes, because the two extremes of the phenotype distribution are selected against. Consider human height as an example of this type of selection and think of a normally distributed Bell curve.
What does natural selection directly work on?
Natural selection acts on the genotype, but indirectly, through the phenotype.
Does selection operate on the genotype or the phenotype?
Natural selection operates on the phenotype.

What natural selection called at extreme phenotype?
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.
Does stabilizing selection favors average individuals?
Yes, because the two extremes of the phenotype distribution are selected against. Consider human height as an example of this type of selection and think of a normally distributed Bell curve.
What does natural selection directly work on?
Natural selection acts on the genotype, but indirectly, through the phenotype.
Which type of natural selection occurs when the extreme opposites in a phenotype range are selected?
Disruptive selection, also known as diversifying selection.
Why is phenotype variation necessary for natural selection and sexual selection?
It is necessary to create a full and varied species.
