Correct answer: (2) the gametes of either parent

Mutation can only cause a change in the next generations if it occurs in the sex cells or gametes of either parent and alters their genetic information. Mutation that occurs in the body cells, such as skin cells and nerve cells, will not affect the offspring because these cells would not be involved in the fertilization of new offsprings.

Incorrect answers:

(1) the skin cells of the mother

Mutations that occurr in the skin cells will not affect the DNA of the offspring because body cells are not involved in fertilization of the formation of offsprings.

(3) all the body cells of both parents

The mutation of body cells will not cause an alteration in the DNA because they do not contribute during fertilization. Only mutated sex cells or gametes may cause a transformation in the genetic information of the offspring.

(4) only the nerve cells of the father

A nerve cell is an example of a body cell. When body cells are mutated, the changes are not passed on to the next generation because only the mutated gametes or sex cells are involved in the formation of offspring.
