"Both RW (I^R I^r)" is the correct choice.

Reason: RW × RW (heterozygote × heterozygote) gives a Punnett square of 1 RR : 2 RW : 1 WW, so you can get RR, RW and WW offspring.
- RW × WW would give 1 RW : 1 WW (no RR).
- RW × RR would give 1 RR : 1 RW (no WW).

If the offspring include all three genotypes/phenotypes, the parents must both be RW. If you want, tell me the observed offspring and I’ll confirm the cross.
