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)

0.5

Answer 1

The tall allele (P) is dominant, while the short phenotype (p) is recessive.

When a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp), there is a 50% chance of passing on the recessive allele to each offspring.

Therefore, the frequency of short offspring (pp) is 0.5 or 50%.
