It is through mutation.
Mutation
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.
For external reproduction, plants that live in moist environments, need water to transport their gametes to enable sperm and egg cells to meet. For internal fertilization, the water holds enough nutrients to support and hold the embryo in the female.
the mutation can be a sources of genetic variety.
Alcohol - from any source, not just vodka - is harmful to several parts of the body, including the reproductive system.
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.
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.
The answer is sexual reproduction
Sexual reproduction.
The phenotypic variations in plants and animals governed by different genes result from sexual reproduction and are source of evolution.
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.
Mutation.
Sexual reproduction is a source of genetic variation. Recombination of chromosomes during meiosis allows for the exchange of DNA, also known as independent assortment. Random segregation also plays a role, as well as some mutations to change the phenotype within different offspring.

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.
