Question
If you cross dominant genotype PV/PV male Drosophila with double recessive female and obtain F1 hybrid. Now you cross F1 male with double recessive female.
What is the possible genotype in the F2 generation?
Solution
F2 hybrids with their genotypes
| PV | Pv | pV | Pv | |
| PV | PPVV | PPVv | PpVV | PpVv |
| Pv | PPVV | PPVv | pPvV | PpVV |
| PV | PpVV | PpVv | ppVV | ppVv |
| Pv | PpVv | Ppvv | ppVv | ppvv |
