MCQ
A Across 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

Answer

  1. Tt and Tt.

In case of TT and Tt; all offspring would be tall (TT, Tt). In case of option ‘c’ no gene for dwarf is present, so all offspring will be tall. In case of option ‘d’ one of the parent plant is dwarf, so it is incorrect. In case of option ‘b’ most of the offspring will be tall and a few will be dwarf (TT, Tt, tt). Option ‘b’ is the correct answer.
