Answer:
C. There is a 25% chance of short offspring.
Explanation:
In the simplified genotypes of a Punnett square cross, we deal with two genotypes. In this case, we are looking at a cross between Tt and Tt. T is dominant and t is recessive, meaning that someone with any genotype with T in it will be tall.
TT, Tt, and Tt will all produce tall offspring, while tt will produce short offspring.
This means there is a 75% chance of tall offspring, or 3:4.
50% or 2:4 are expected to have the Tt genotype.
Only 1 of the 4 will produce short offspring, which is 25%.
