yeast cells splitting into new cells bacteria cells dividing into new cells skin cells dividing to produce more skin cells sperm and egg cells uniting to produce fertilized egg cells
I gave my students this multiple choice question: Which example would result in new cells that are most different from the parent cells?

Only one answer is correct among these 4 choices:
- yeast cells splitting into new cells
- bacteria cells dividing into new cells
- skin cells dividing to produce more skin cells
- sperm and egg cells uniting to produce fertilized egg cells

Could you tell me which one is correct?

sperm and egg cells uniting to produce fertilized egg cells
