Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
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 is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis?
Crossing over, or genetic recombination, is the process in meiosis where sections of chromosomes are exchanged between homologous chromosomes, leading to genetic variation in offspring. This event occurs during prophase I of meiosis.
What can mutations be a source of?
Mutations create changes in the genetic code. There are different types of mutations and vary in degree of harm or even benefit to the organism. If the mutation happens to be beneficial to the organism, then it can be passed down to its offspring and thus this leads to genetic variation in the population.
What process is responsible for genetic variation?
The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.
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.?
Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
What is the source of genetic variation that refers to random error in the genetic code?
Mutations
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
