Mutation.
No. Asexual reproduction provides no diversity, as it creates an exact copy of the organism. Sexual reproduction, on the other hand, provides diversity by using and combining different genes each time to create an entirely new version of the organism.
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.?
The main source of genetic variation is a large population with a large gene pool.
It is through mutation.

Things that kill the organism, such as, immature lungs at birth.
The answer is sexual reproduction
Sexual reproduction is more advantageous than asexual reproduction because it allows for genetic diversity. In asexual reproduction there is only one source of genetic material whereas with sexual reproduction there are two sources of genetic material.
When alleles are recombined during sexual reproduction, they can produce dramatically different phenotypes. Thus, sexual reproduction is a major source of variation within many population.
Human recombination is a significant source of genetic variation.
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 .
There is no difference. Sexual reproduction is a source of genetic variation. Because during sexual reproduction within humans, a sperm cell and egg, each consisting of different genetic codes, combine to form a completely different DNA. Immediately, a genetic variation occurs between the parents and the offspring because of the union of the gamete cells, a sperm and egg.
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.
