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

O 0.5

O 0.25

O 0.75

Ο 1.0

1 answer

The Punnett square for this cross would be as follows:

P p
P PP Pp
p Pp pp

So, in this cross, 50% of the offspring will have the genotype pp (short). Therefore, the frequency of short offspring (pp) would be 0.5.

Therefore, the correct answer is: 0.5.
