Guinea pigs have dark fur (D) or white fur (d). They also have a rough coat (R) or a smooth coat (r). If two guinea pigs that are heterozygous for both traits are crossed, what are the expected phenotypes of the offspring?
- All the offspring will have dark fur and a rough coat.

- There will be a mixture of dark/rough, dark/smooth, white/rough, and white/smooth offspring.
- There will only be dark/rough and white/smooth offspring.
