Which statements about mutations are true? Check all that apply. Mutations cannot be passed from generation to generation. Mutations are rare. Mutations are always harmful. Germline mutations occur in body cells. Most forms of cancer are caused by somatic mutations.

Answer 1

Answer;

• Mutations are rare.
• Most forms of cancer are caused by somatic mutations.

Explanation;

• Mutations are sudden spontaneous and random changes that occurs in the genetic make up of an organism. They are alterations that occur in the nucleotide sequences in the genetic make up or the genome of organisms.
• Mutations are rare but when they occur they may be advantageous or disadvantageous to an organism. Advantageous mutations have allowed organisms to adapt to their environment, and also resistance to diseases such as malaria in sickle cell.
• However mutations may have disadvantageous and deadly effects, for example most of cancer are caused by somatic mutations or mutations in the body cells.

Answer 2

Mutations are rare, Most forms of cancer are caused by somatic mutations, and (I think) Germline mutations occur in body cells.
