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
1.0
The frequency of the short offspring (pp) can be determined using the Punnett square method.
Let's consider the alleles of the tall pea plant with one tall allele (Pp):
P = tall allele
p = short allele
And the alleles of the short pea plant (pp):
p = short allele
The possible combinations of alleles in the offspring are:
1. Pp (tall)
2. pp (short)
Since the tall allele (P) is dominant, only one copy is necessary for the offspring to be tall.
Therefore, the frequency of the short offspring (pp) would be 0.25 or 25%.
Answer: 0.25
