If the offspring of a particular cross are 100 percent heterozygous for the trait of plant height. the most likely genotypes of the parents is TT and tt.
Heterozygosity is a condition in which the genotype of an individual consists of two different alleles of a gene.
According to this question, a gene coding for plant height is involved. The tall allele (T) is dominant over the short allele (t).
This means a heterozygous offspring will have the following genotype: Tt. This genotype will only arise totally i.e. 100% in the offsprings if the parents are both homzygous for the trait i.e. TT and tt.
