Red eyes in fruit flies are dominant over white eyes using punnet squares find the possible eye colors of the F1 generation of each of the following crosses Rr x rr, rr x RR, Rr x Rr
1. **Rr x rr**: - Rr (parent 1) x rr (parent 2) - Possible genotypes in the F1 generation: Rr and Rr - Possible eye colors: Red eyes (Rr) only
2. **rr x RR**: - rr (parent 1) x RR (parent 2) - Possible genotypes in the F1 generation: Rr and Rr - Possible eye colors: Red eyes (Rr) only
3. **Rr x Rr**: - Rr (parent 1) x Rr (parent 2) - Possible genotypes in the F1 generation: RR, Rr, Rr, and rr - Possible eye colors: Red eyes (RR, Rr) and white eyes (rr)
