A cross between two tall plants resulted in offspring having few dwarf plants. What would be the genotypes of both the parents?
a. TT and Tt
b. Tt and Tt
c. TT and TT
d. Tt and tt
The answer is the option (b) Tt and Tt
Explanation: In the case of Tt and Tt (option (b)), a few of the offspring will be dwarf (TT, Tt, tt) and most of them are going to be tall (TT, Tt). In case of option (a) and (c), the offspring will be all tall and in option (d), one of the parent is dwarf. Hence, (b) is the correct option.
