Work out a dihybrid cross between homozygous tall pea plant bearing round seed and dwarf pea plant with wrinkled seed for 2 generation. Also use the punnet square box method.
Dihybrid cross
Parents- Tall pea plant bearing round seed- TTRR & dwarf pea plant with wrinkled seed- ttrr
TTRR x ttrr
Gametes- TR & tr
F1 generation- TtRr
The F1 generation produced is self crossed, as shown below-
| Gametes | TR | Tr | tR | tr |
| TR | TTRR (tall & round) | TTRr(Tall & round) | TtRR(Tall & Round) | TtRr(Tall & Round) |
| Tr | TTRr(Tall & Round) | TTrr(Tall & wrinkled) | TtRr(Tall & Round) | Ttrr(Tall & wrinkled) |
| tR | TtRR(Tall & Round) | TtRr(Tall & Round) | ttRR( Dwarf& round) | ttRr( Dwarf& round) |
| tr | TtRr (Tall & Round) | Ttrr(Tall & wrinkled) | ttRr( Dwarf& round) | ttrr(Dwarf & wrinkled) |
