Question
If one parent is dominant tall, and one parent is mixed hybrid, what is the genotype ratio for the possible offspring? Use the reference sheet below to answer.
TT = dominant tall (genotype tall, phenotype tall)
Tt = mixed hybrid (genotype hybrid, phenotype tallI)
tt = recessive short (genotype short, phenotype short)
T.

Both parents are dominant
tall so all offspring are tall.
Both parents are mixed hybrids
so offspring are a 3:1 ratio.
