Example of incomplete dominance.
anthocyanin, a flavonoid that gives petals a deep red color.
It is synthesized from a white precursor by the enzyme anthocyanin synthase, which is coded by the ANS gene. The gene has two alleles: A (functional) and a (inactive)
AA: produces lots of anthocyanin--> red
Aa: some anthocyanin synthase is made--> pink
aa--> white due to no anthocyanin
