Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
Evolution by natural selection works best on populatin having no variation?
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
Does natural selection require genetic variation in order to drive the process of evolution?
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.
Differences between organisms of the same species are known as?

Does natural selection increase or decrease variation in a population?
Natural selection tends to decrease variation in a population by favoring certain traits that are better suited for survival and reproduction. As individuals with advantageous traits have higher fitness, their genes are passed on more frequently, reducing the frequency of less beneficial traits in the population over time.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
What requires natural selection to occur in a population?
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.
Is it possible for a population to undergo natural selection?
No, there is no genetic variation upon which natural selection can operate.
Does natural selection work on a variation already present in a population?
Yes.
Does natural selection have a tendency to increase or decrease genetic variation within a population?
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
Can natural selection act on a population with no variation traits?
The trait is the same for all organisms.
In order for evolution by natural selection to occur what has to happen?
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
What id genetic variation?
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
Natural selection acts on variation by?
Natural selection acts on variation by picking out from a population's gene pool those that are more fit to survive. More variation leads to more natural selection. For example, currently endangered cheetas are found out to have less genetic variation than other animals. As a result, if a disatrouous event occured, there are no genes that could help the cheetas survived. Thus, natural selection prevent the cheetas from reproducing as a population and they become extinct.
