Mutations serve up the variations in organisms to natural selection. The reproductively successful variations pass on these successful traits to progeny and allele frequencies change because of this and this is evolution.

What are the mechanisms of evolution?
There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations. Genetic drift is also another important aspect of evolution. EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism.

How does chance play a role in evolution?
Evolution is caused by adaptations (favorable traits) that sometimes come from mutations. Mutations happen by chance, and this is how chance plays a role in evolution.
Evaluate the significance of mutations and repair of mutations to the evolution of sexual reproduction?
evaluate the significance of mutations and repairof mutations to the evolution of sexual reproduction
Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Mutations such as polyploidy and crossing over provide the genetic basis for?
evolution

True or false Mutations can increase the variations in a species 'traits?
Mutations are important for evolution because they provide the variability whereupon natural selection acts.true last answered by zaporia
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

Is evolution good or bad?
Genetic mutations can be good or bad, but evolution refers specifically to those mutations that make an organism better able to survive and to perpetuate their species, which makes them generally a good thing.
What provide the new material on which evolution can act b.Genetic conservation c. Mutations d. Phenotypes a. Trader Joe's's .?
Mutations is the correct answer.
Mutations that occur in skin or lung cells have little effect on the evolution of a species because mutations in these cells?
cannot be passed on to offspring
