Phenotype and Genotype:

  • In the first generation, all the plants will have a genotype of Tt.
  • Since, tall is the dominant characters, so all the plants will be tall.
  • If we take these and cross with each other, then each of the gamates can be T or t, therefore one plant will have a genotype of TT (homozygous tall) two plants will have the genotype of Tt (heterozygous tall) and one plant will have tt (homozygous short).
