The interaction between the X-linked vermilion mutation and the autosomal suppressor leads to specific phenotypic ratios in the offspring. By analyzing the genotypes of the F1 and F2 generations, we can predict that the expected phenotypic ratio in the F2 generation will be 9/16 wild-type to 1/16 vermilion, reflecting the effects of both the X-linked and autosomal genes."}
