In sexual reproduction, two parents combine their geneticmaterial to form a new organim. Meanwhile, genetic variation can give the new organism a helpful trait or unhelpful trait that would affect its life and how it could life in a certain enviornment.
huh
Genetic variation
There is genetic variation in the sea stars as a result of sexual reproduction.
Genetic variation
Mutation.
The answer is sexual reproduction
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
greater genetic variation. (e2020 answer)
both
It promotes genetic variation.
Sexual reproduction (using meiosis) provides genetic variation because the two parent's traits are combined. With asexual reproduction, the parent gene is just duplicated.
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
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.
