|
Would a mutation in the DNA of a skin cell be passed on to an organism’s offspring?
|
|
Yes, because any change to the DNA is passed on to the offspring
|
|
|
Maybe. Sex cells only use half of the body’s genetic code. It might get the copy of a gene that wasn’t mutated.
|
|
|
No. Only mutations that occur in the gametes (sex cells) are passed on to the offspring
|
|
|
Without knowing the animal, it would be hard to tell whether or not the mutation would be passed on.

Explanation:
Detailed explanation-1: -Somatic mutations occur in non-reproductive cells; they are passed to daughter cells during mitosis but not to offspring during sexual reproduction.
Detailed explanation-2: -Most often, gene changes related to melanoma are acquired during a person’s lifetime and are not passed on to a person’s children (inherited). In some cases, these acquired mutations seem to happen randomly within a cell, without having a clear cause.
