Explanation:

The initial cell formed at fertilisation is a combination of the sperm and egg cell from which every other cell is derived. If a mutation occurs here, it will likely be passed to every subsequent cell. However, if it's a normal body (somatic) cell from a fully grown adult, it will only affect that particular cell and any from that small part of the body.
