Answer: The possible genotype is Tt.
Phenotype: Tt = tall pea plant chances of having Tt is 100% because all the offsprings have genotype Tt.
Explanation: A cross between a pea plant with genotype TT and another with genotype tt will produce four offsprings, all with genotype Tt.
TT x tt = Tt, Tt, Tt, and Tt. All the offsprings have genotype Tt.
Since tall height is dominant to short height, Tt will manifest outwardly as tall pea plants.
The chances of having an offspring with Tt genotype is 100% because all of the four offsprings have Tt genotype.
