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 (Pp) is cross-pollinated with a short pea plant (pp)?(1 point)

The frequency of short offspring (pp) can be determined using the Punnett square method.
When a tall pea plant (Pp) is cross-pollinated with a short pea plant (pp), the possible genotypes of the offspring are Pp and pp.
Pp x pp
P p
---------
Pp pp
Therefore, out of the four possible combinations, two of them (50%) result in the short phenotype (pp).
So, the correct answer is 0.5.
