In a garden, you noticed that one plant produces flowers with one of three different colors: red, blue, and black. After being intrigued by this discovery, you decide to collect samples and run various biological analyses to determine which genes control flower color. Analysis showed that flower color is controlled by two genes that you labeled as "Gene A" and "Gene B", with a functional Gene A being epistatic to Gene B. You also learn that Gene A has two alleles, with allele A1 (Functional Black Petal Pigment Gene) being dominant to allele A2 (Non-Functional Black Petal Pigment Gene; No Gene Expression). Gene B also has two alleles, with allele B1 (Functional Blue Petal Pigment Gene) being dominant to allele B2 (Functional Red Petal Pigment Gene). An experiment was performed crossing a true-breeding black dahlia with a true-breeding red dahlia. The resulting progeny were intercrossed and the following F2 were observed: 80 Black dahlia 20 Red dahlia A) Based on the described experiment, what F2 phenotypes and proportions (provided as a ratio) would you have expected?
