The offspring of a particular cross are 100 percent heterozygous for tallness. what were the most likely genotypes of the parents?
tt x tt
tt x tt
tt x tt
tt x tt

Genotypes of the parents is TT and tt.

According to the given situation, offsprings of the cross are heterozygous. This means that the genotype of offsprings is Tt. This is only possible when the parents of the offspring are pure breeding homozygous dominant and homozygous recessive. The result can further be justified using punnett square analysis. Refer the attachment for this.
