What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing Over.
Why is crossing over so important?
It increases genetic variation in organisms
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is the source of genetic variation that refers to random error in the genetic code?
Mutations
What is the source of genetic variation in asexual reproduction?
Mutation.
Which of these is not a source of genetic variation in a population?
The answer is sexual reproduction
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.
Which of these is NOT a source of genetic recombination and variation?
A piece of volcanic rock.
Is genetic recombination a major source of variation among organisms?
Yes.
What is the ultimate source of genetic variation and the basis for the diversity of on earth?
mutation
