In a dihybrid cross involving two unlinked genes (Gene A and Gene B) with standard dominance, they exhibit epistasis where the recessive genotype for Gene A (aa) masks the expression of Gene B. What is the expected phenotypic ratio in the F2 generation following a cross between two F1 heterozygotes (AaBb x AaBb)?
