Yes; Mutations in somatic cells only affect the person they occur in. This is because somatic cells undergo meiosis, and cells made through mitosis are YOUR cells are only affect you. Only mutations in your germ-line cells (cells in your reproductive organs that lead to sperm and egg cells) can be passed on!

b)

No; Mutations in somatic cells only affect the person they occur in. This is because somatic cells undergo mitosis, and cells made through mitosis are YOUR cells are only affect you. Only mutations in your germ-line cells (cells in your reproductive organs that lead to sperm and egg cells) can be passed on!
