In a flowering plant, gene "A" encodes an enzyme responsible for the presence of dots on the flowers’ petals. A1, A2, and A3 are the three known alleles of this gene; A1 is the wild type, A2 is a null allele that makes no product, while A3 has a mutation in the promoter region of the gene, which results in the synthesis of very little gene product. If the "A" gene is haploinsufficient, what is the predicted phenotypic ratio in the F1 of a cross between a wild type and a A2/A3 heterozygous?
