No, natural selection works on that genetic variation presented to it.
no there is no genetic variation for natural selection to act upon
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.
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
Genetic variation is important because it allows for diversity within a population, which increases the chances of survival in changing environments. Natural selection acts on this variation, favoring traits that increase an organism's fitness and leading to adaptation and evolution over time.
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, there is no genetic variation upon which natural selection can operate.
no there is no genetic variation for natural selection to act upon
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
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.
Without variation there is nothing to select from.
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population

Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Genetic drift can reduce genetic variation within a population, making it harder for natural selection to act upon beneficial traits. Gene flow, on the other hand, can introduce new genetic variation into a population, potentially increasing the pool of traits for natural selection to act upon. Overall, both genetic drift and gene flow can influence the effectiveness of natural selection by altering the genetic composition of populations.
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.
