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-
