The following question was on a pretest of mine, and I'm trying to figure out the answer using what we've learned about Mendelian and non-Mendelian patterns of inheritance. I'm struggling quite a lot with this question; I'm not sure if that's because of me or if the question itself is poor/confusing.
I don't know what the answer actually is, as there was no answer key to go along with the exam. My best guess is that the pattern of inheritance is Incomplete Dominance based on the Red x Yellow cross and the fact that neither allele was dominant over the other in the resulting progeny. But is it even possible to state this with full confidence? What about the other crosses?
In a plant species, plants may produce red, yellow, or orange flowers. The table below shows the results of crosses between the plants that produce each flower color.
Based on this information, which pattern of inheritance controls flower color in this plant species?
(A) Codominance
(B) Complete dominance
(C) Incomplete dominance
(D) Multiple alleles
