How would a mutation in skin cell differ from a mutation within a sperm or egg cell in relation to the theory of evolu tion?

If a mutation occurs in the skin cell, it only affects that individual. However, a mutation in the sperm or egg results in altered DNA, which can be passed onto the offspring. Eventually, this can result in genetic changes which are either favored or not. This relates to the survival of the fittest because those with mutations that help individuals survive pass those mutations onto their offspring.
