Question

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)📝 Responses( ) 0.5( ) 0.75( ) 1.0( ) 0.25

GPT-5 mini · Answer

Answer: 0.5

Explanation: Cross Pp × pp → gametes P or p (½ each) from the tall plant and p from the short. Offspring: ½ Pp (tall) and ½ pp (short), so short = 0.5 (50%).
