Tall vine being dominant and short plant being recessive, let's suppose the homozygous tall vine is represented by TT and the homozygous short plant is represented by tt. When these two are crossed with each other, following genotypes are obtained in the F1 generation:

TT x tt

Tt, Tt, Tt, Tt

A heterozygous combination is achieved for all the offspring with tall vine as the phenotype, and the recessive gene for the short plant present in the genotype.
