What difference does it make if a mutation occurs in a somatic cell or in a gamete?
If the mutation occurs in a somatic cell and the cell is still able to reproduce, the mutation continues in the daughter cells in following generations. If a mutation occurs in a gamete, the original organism remains unchanged. If that gamete is used for reproduction, then the mutation will continue in the offspring.

Who does somatic mutation affect?
A somatic mutation is one that occurs in any body cell with the exception of the gametes (sperm and eggs). A somatic mutation cannot be passed on to offspring, so it affects only the person with the mutation.
Why are somatic mutations generally less important than germ mutations?
Because the somatic mutation only produces the color of the iris of the eye. The germ mutation is in charge of the cell which will produce a gamete. It may be passed onto the offspring. So the somatic mutation isn't as important as the germ mutation.
Are mutations heritable?
Yes, mutations are heritable if they occur in germ cells (sperm or egg cells) as they can be passed on to offspring. However, mutations that occur in somatic cells (non-reproductive cells) are not heritable.
What is the difference between somatic and gametic cells?
a germline mutation is one the was passed on to offspring because the egg or sperm cell was mutated. a somatic mutation is a mutation of the somatic cells (all cells except sex cells) that cannot be passed on to offspring.
What is difference between somaclonal and gemetoclonal 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.

If mutation occurs in somatic cells could the change be passed on by the mutant to its offspring?
Not with natural reproduction. If you cloned the parent that had the somatic mutation, you could pass it on to the offspring if you used the nucleus from the cell that had the somatic mutation.
A mutation that occurs in a diploid cell can be inherited only if?
Mutation occurs in a cell that produces gemetes
How are mutations are inherited?
If a mutation occurs in a sex cell, then it may be inherited. Any mutation to the somatic cells will not be passed on. Any mutations that either of the parent organisms have will be inherited by their offspring.
Would a mutation be worse if it was in a gamete or in a regular body cell?
A mutation in a gamete would be more concerning because it can be passed on to offspring and potentially affect future generations. In contrast, a mutation in a regular body cell would generally only affect the individual in which it occurs.
Could a mutation in a cell in the liver of a human be passed on?
For a mutation to be passed onto the next generation it must be on sex chromosome. If mutation occurs in somatic cells of our body, it will not be passed on to the offspring(s). Mutation that changes one or few base pairs in the DNA is called point mutation.
How does the possible impact of a chromosomal mutation that occurs during meiosis differ from that of a similar event that occurs during mitosis of a body cell not involved in reproduction?
A chromosomal mutation during meiosis can result in genetic variability in offspring due to the formation of gametes with altered chromosomes. In contrast, a similar mutation during mitosis of a body cell not involved in reproduction can lead to a mosaic pattern of affected and unaffected cells in the individual's body. This can result in a localized impact on tissues or organs depending on the extent of mosaicism.
What are difference between antigen drift and antigenic shift?
Both are mutation occurs in virus (usually influenza). But the difference is: antigenic drift are mutation occurs in viral DNA/RNA that cause a person to be re-infected by the virus. while antigenic shift are mutation occurs in viral characteristic, which cause transition from being able to infect poultry ONLY (not human), --> able to infect BOTH poultry and human.
Where does mitosis occurs?
occurs in all the somatic (body) cells
What happens if mutations occur in somatic cells of an organism?
A somatic mutation is one that occurs AFTER offspring have been conceived. This means that the mutations are not passed on to the f2 generation of offspring. An example we find in humans is cancer.
Are mutations heritable?
Yes, mutations are heritable if they occur in germ cells (sperm or egg cells) as they can be passed on to offspring. However, mutations that occur in somatic cells (non-reproductive cells) are not heritable.
