The probability of an offspring being short is determined by the genotype of the parents. In this case, both parents are heterozygous, meaning they carry one dominant allele (T) for tallness and one recessive allele (t) for shortness.
The Punnett square for this cross would be as follows:
Tt x Tt
The possible genotypes of the offspring are: TT, Tt, Tt, and tt. Out of these, only the genotype tt represents a short plant. Therefore, there is a 25% chance that an offspring will be short.
The correct answer is C. 25%.
