Answer 2

Hi there!

`\large\boxed{\text{C. rr}}`

In the given situation, a rough coat (R) is dominant over the smooth coat (r).

For a guinea pig to express the recessive smooth coat trait, they must not contain any dominant alleles in their genotype.

Therefore, the only possible genotype would be both recessive, or C. rr.
