Answer: The phenotype ratio is 3:1

Explanation: If T represents tall trait and is dominant over t which is the recessive trait, there are 1 homozygous tall (TT), 2 heterozygous tall (Tt) and 1 homozygous short (tt) offsprings. All homozygous tall and heterozygous tall offsprings will appear outwardly as tall while the homozygous short offspring will appear outwardly as short. Therefore the phenotype ratio is 3:1
