Question
The plant Rafflesia arnoldi has one of the largest flowers on record (about the size of an umbrella). The flower can be
gold or brown, and may emit a fragrance of perfume or rotting meat. Assume that each trait is caused by a single
gene in which one allele is completely dominant to the other and that these genes are independently assorting.
The following table shows the resulting offspring produced by mating parents of the indicated phenotypes.
