What type of cross is between TT and tt plants?

Options

  1. ADihybrid cross
  2. BMonohybrid cross
  3. CTrihybrid cross
  4. DSelf-cross

Correct answer

B. Monohybrid cross

Step-by-step solution

The Tt plant is heterozygous for genes controlling one character (height), it is a monohybrid and the cross between TT and tt is a monohybrid cross. From the observation that the recessive parental trait is expressed without any blending in the F2 generation, we can infer that, when the tall and dwarf plant produce gametes, by the process of meiosis.
