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) Responses 0.25 0.25 1.0 1.0 0.5 0.5 0.75
The frequency of short offspring (pp) in this cross can be determined using the Punnett square.
When a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp), the possible genotypes of the offspring are: Pp and pp.
The probability of getting offspring with the pp genotype is 1/4 or 0.25.
Therefore, the frequency of short offspring (pp) is 0.25.
