Explanation:
Detailed explanation-1: -As the given genotype is Tt, it’s a heterozygous condition and in heterozygous condition the dominant trait (T-tall) will express itself. Hence, the phenotype of Tt will be a tall plant. Q.
Detailed explanation-2: -Pea plants are tall if they have the genotype TT or Tt, and they are short if they have genotype tt. A tall plant is mated with a short plant. Which outcome below would indicate that the tall parent plant was heterozygous? All of the offspring are short.
Detailed explanation-3: -Answer and Explanation: A tall pea plant with (TT) and a tall pea plant with (Tt) have the same phenotype but different genotypes. Phenotype is the appearance (trait), both plants appear tall.
