Answer:
Gametes
Step-by-step explanation:
The cells that make an organism, and therefore pass on DNA from the parent to the next generation, are the egg and sperm cells, also called the gametes.
Egg and sperm cells are haploid, which means when they fuse, they make a diploid cell. This cell produces all the cells in the body of a new organism.
Only mutations that occur in these cells will make it to the offspring. If a mutation occurs, for example, in the skin cells or brain cells, they might affect the individual, but they will not be passed on to the next generation.
