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.
