Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
No, natural selection works on that genetic variation presented to it.
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.
no there is no genetic variation for natural selection to act upon
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
no there is no genetic variation for natural selection to act upon
No, there is no genetic variation upon which natural selection can operate.
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.

Genetic variation is one of the conditions required for Natural Selection to occur.
Natural Selection.
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
