Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
How is change by natural selection different from change due to a mutation?
Change by natural selection occurs when certain traits provide a survival or reproductive advantage in a given environment, leading to those traits becoming more common in a population over generations. In contrast, a mutation is a random change in an organism's DNA that can introduce new traits. While mutations are the source of genetic variation, natural selection acts on that variation, favoring beneficial mutations and weeding out harmful ones. Thus, mutations are the raw material for evolution, while natural selection is the mechanism that drives adaptive change.
What constantly provides new variation for natural selection to act upon in a sexually reproducing popularion?
Firstly, mutation. In a sexually reproducing population recombination ( independent orientation of chromosomes and crossing over in meiosis and random fertilization ) is also a source of variation in populations.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )

What is a major cause of variation within species?
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
The original source of genetic variation that serves as the raw material for natural selection is what?
Generally, mutation.
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
What effect does mutations have on variation?
Mutations are a source of genetic variation as they introduce new alleles into a population. They can lead to differences in physical characteristics, behavior, or susceptibility to diseases within a species. Over time, mutations can contribute to evolution by providing the raw material for natural selection to act upon, ultimately driving changes in a population.

Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
Why are mutation and recombination important in the process of natural selection and the evolution of organisms?
When a mutation occurs in the replication process, it changes certain features, like maybe better eyesight, and maybe bigger eyes, or bigger claws, and the meaning of evolution is when something changes into a better form.
