- C. the environment.
- D. a random occurrence.
4. If scientists are studying a family of dogs and notice that most of the puppies have floppy ears just like their parents, what does this pattern suggest?

- B. Because it is a rule that all studies must be large.
- C. To find reliable patterns that appear across different groups.
- D. To prove that every single offspring is identical to its parent.
