Step-by-step explanation:
So a homozygous dominant tall plant would be TT, and a homozygous recessive short plant would be tt. If you put these into a punnett square, you would get 4 Tt's since each offspring gets one allele from each parent and being tall is dominant. The phenotype of Tt (what it looks like) is tall which means they are all tall and none are short.
