In the dog breed known as labrador retrievers, coat color is controlled by the epistatic genes b and e. in the absence of a dominant e allele, coat color is yellow regardless of the b genotype. if a dominant e allele is present, a b allele gives a black coat, whereas the homozygous bb genotype gives a chocolate (brown) coat. the figure shows the genotypes and phenotypes that result from a dihybrid cross between two bb ee individuals. review the genotypes and phenotypes shown, and then match each of the genotypes on the left with the correct statement of breeding outcome to review inheritance of recessively epistatic genes.

The result from a dihybrid cross between two BbEe individuals will result in

4 Homodominant, 8 Heter and 4 Homorecessive.

Explanation:

Epistasis is the phenomenon where the result or effect of one gene depends on the presence of other genes, in other words, one genes does not allow to alleles of other locus to express, then their phenotype (physical appearance) will depend on the sorting of the two (or more) genes involved.
