In Ursa gummi, the famed Gummy Bear soldiers, a quality that is sought is bravery (dominant phenotype). The recessive phenotype

is timidity or conformity. The alleles and genotypes corresponding to these phenotypes at two loci are presented below. A_ codes for brave; aa codes for timid/conforming; B_ codes for brave; bb codes for timid/conforming. What is the phenotypic ratio of brave:timid offspring from a cross between two doubly heterozygous Ursa gummi, if the mode of inheritance is duplicate recessive epistasis?
