A black Labrador, Three phenotype of black, brown and yellow is control by non allelic gene interaction. Following some genotype

 The following conclusions were made

A. The 9:3:4 ratio obtained upon selfing of AaBb here indicates recessive epistasis

B. This is a recessive epistasis where homozygous bb is epistatic to A and a.

C. When Gene A and B incompletely link, It will be produced all phenotype black, brown and yellow upon selfing of AaBb

D. When Gene A and B incompletely link, test cross of AaBb will be produced all phenotype black, brown and yellow in ratio 1:1:2 respectively
