WebSince all cells in our body contain DNA, there are lots of places for mutations to occur; however, not all mutations matter for evolution. Somatic mutations occur in non-reproductive cells and so won’t be passed on to offspring. For example, the yellow color on half of a petal on this red tulip was caused by a somatic.
