In a species of Asclepias (milkweeds) there are two alleles of a gene involved in the synthesis of cardenolides. One allele results in normal synthesis of these molecules, while the other allele prevents synthesis from occurring. Individuals who are heterozygous for this gene produce intermediate amounts of cardenolides. In a population of Asclepias where both alleles of the cardenolide synthesis allele are present the following phenotypes were observed: Normal cardenolide concentration: 241
Intermediate cardenolide concentration: 720
No cardenolides: 39
What are the expected phenotypic frequencies in this population?
A. Normal: 0.36; Intermediate: 0.62; No cardenolides: 0.02
B. Normal: 0.36; Intermediate: 0.48; No cardenolides: 0.16
C. Normal: 0.24; Intermediate: 0.48; No cardenolides: 0.04
D. Normal: 0.50; Intermediate: 0.48; No cardenolides: 0.02
E. Normal: 0.24; Intermediate: 0.72; No cardenolides: 0.04
