A true-breeding black goose from Nova Scotia is crossed with true-breeding black goose from Japan, producing F1 offspring that are all gray. The F1s are intercrossed, producing F2s with the following phenotypes: 37 gray and 29 black. Other research has revealed that feather color is controlled by two genes in geese. What type of epistasis best fits this phenotypic ratio?

A) Dominant epistasis  
B)
Duplicate recessive epistasis   
C)
There is no epistasis in this cross.  
D)
Recessive epistasis    
E)
Duplicate dominant epistasis
