Detailed explanation-1: -Which statement best explains why people with cancer due to asbestos exposure do not pass the mutation on to their offspring? The mutation occurred in somatic cells.
Detailed explanation-2: -Mutations in somatic cells are called somatic mutations. Because they do not occur in cells that give rise to gametes, the mutation is not passed along to the next generation by sexual means.
Detailed explanation-3: -Mutations in the DNA of somatic/body cells cannot affect the individual in which they happen. A mutation in the DNA of a gamete affects the somatic/body cells of the individual that produced the gamete.
