Dear student,
The tallness or shortness of pea plant depends on the genotype of the plant. A pea plant with genotype TT or Tt, will be tall whereas a plant with genotype tt is a short plant. Since tallness is dominant over recessive, a plant can be short only if it has both genes for shortness i.e. tt.
