A tall pea plant results from a dominant tall allele while the short phenotype results from two recessive alleles. What is the frequency of short offspring (pp) when a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp)?(1 point)

When a tall pea plant (Pp) is crossed with a short pea plant (pp), the Punnett square would show that half of the offspring would inherit one short allele from the short parent, resulting in a genotype of Pp (tall). The other half of the offspring would inherit two short alleles from both parents, resulting in a genotype of pp (short). Therefore, the frequency of short offspring (pp) would be 0.5 or 50%.
