Q. When a tall pea plant (TT) is crossed with dwarf plant (tt) what will be the F2-generation?
A) All tall plants
B) All dwarf plants
C) Both tall and dwarf plants in 1 : 1 ratio
D) Both tall and dwarf plants in 3 : 1 ratio
Explanation
When a tall pea plant (TT) is crossed with dwarf plant (tt), the F1progeny shows all plants hybrid tall and on selfing of F1progeny, the F2generation shows both tall and dwarf plant in the ratio 3 : 1. Out of three tall plants, one is pure tall (TT) and two are hybrid tall (Tt).
