Mutations that occur in the somatic cells are called somatic variations .New mutations occur twice as frequently in sperm as in eggs(germ cells), probably because so many more cell divisions are required to make sperm than eggs.
Somatic mutations, which occur in non-reproductive cells, do not directly lead to speciation because they are not passed on to offspring. Speciation typically involves genetic changes that accumulate in the germline, leading to reproductive isolation between populations. However, somatic mutations can contribute to phenotypic variation within a species and may influence evolutionary processes indirectly, but they are not the primary drivers of speciation.

Genetically identical 1n somatic cells are the final result of the mitosis of a 1n somatic cell. Somatic comes from the Greek word soma, meaning body.
Another name for body cells is somatic cells.
After mitosis, each somatic cell will produce two identical daughter cells. Therefore, if an organism has 24 somatic cells before mitosis, there will be a total of 48 somatic cells after mitosis.
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
Somaclonal variation occurs when plants regenerated from somatic cells show genetic variation due to tissue culture processes, while gametoclonal variation arises from genetic changes in gametes. Somaclonal variation is more common in tissue culture-based regeneration systems, while gametoclonal variation is a result of natural processes during meiosis and gamete formation.

Artificial embryo twinning is achieved by separating an embryo into two similar cells. Somatic cell nuclear transfer (SCNT), on the other hand, is done by replacing an egg cell's set of chromosomes with two from a somatic cell.
