Respuesta :
The most likely resulting phenotype of the offspring would be tall.
Monohybrid crosses
Assuming that height is represented by T (tall) or t (short) in the plant.
Homzygous dominant parent = TT
Heterozygous dominant parent = Tt
Crossing the two parents:
TT x Tt
TT Tt TT Tt
All the offspring from the cross contain, at least, one T in their genotype. meaning that all of them would appear tall phenotypically.
