Question:
In a cross between two tall pea plants some of the offsprings produced were dwarf. Show with the help of a Punnett square how this is possible.
Solution:
Gametes T t
T
TT
Tt
t
Tt
tt
Parent: Tt and Tt
Gametes: T, t
F1 generation: Tt
Gametes: T, t
F2 generation (as shown in Punnett square above)
So, the phenotypic ratio is 3 (tall) : 1 (dwarf)
