Explanation:
Detailed explanation-1: -Germ-line mutations occur in reproductive cells (sperm or eggs) and are passed to an organism’s offspring during sexual reproduction. Somatic mutations occur in non-reproductive cells; they are passed to daughter cells during mitosis but not to offspring during sexual reproduction.
Detailed explanation-2: -Germline mutations occur in a parent’s reproductive cells (egg or sperm). These mutations change the genetic material that the child receives from their parent (hereditary). You can inherit germline mutations from either parent.
