- There are the same number of DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
- There are twice as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
- There are four times as many DNA molecules in an unfertilized egg cell as in a fertilized egg cell.
