Explanation:

According to the question, the allele for tallness (T) is dominant over the allele for shortness (t) in the height gene of pea plants. This means that a short pea plant can only have two recessive alleles (tt).

In this cross, a purebred tall pea plant with genotype; TT is cross-pollinated with a heterozygous tall pea plant with genotype; Tt. The following genotype of gametes will be produced by each parent:

TT- T and T

Tt- T and t

Using these gametes to draw a punnet square (as seen in the attachment), the following offsprings will be produced:

TT (2) and Tt (2) i.e. ratio 1:1

Hence, no offsprings with genotype tt is produced from this cross. This means that the probability of having a short offspring in this cross is 0%.
