A mutation
No, natural selection works on that genetic variation presented to it.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
Mutation.
The main source of genetic variation is a large population with a large gene pool.
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
Mutations
Mutations involve changes in the DNA code.
Human recombination is a significant source of genetic variation.
Independent assortment of chromosomes, crossing over and Random fetiliztion
Mutation.
No, natural selection works on that genetic variation presented to it.
Genetic variation, which can lead to evoloution, and then potentially a new species.
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.?
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.
Mutation.
The answer is sexual reproduction
