State Assessment Review 8th Grade #1

A photograph of a litter of six-week-old bulldog puppies shows that the puppies are not identical. Even though these puppies have the same parents, they do not all look alike because —

• they were produced by asexual cloning

• some of the puppies have genetic material from only one of the parents

• each puppy has a different combination of genetic material as a result of sexual reproduction

• all the puppies developed from the same fertilized egg
