Solid Black,black with Tan Belly,and Agouti Coat Color in Mice $\frac { 1 } { 4 }$

Solid black,black with tan belly,and agouti coat color in mice are all caused by alleles of the agouti gene.All three colors can be true-breeding.When using mice from true-breeding strains: (1) Black × Agouti F₁s are all agouti,(2) Black × Black with Tan belly F₁s are all black and tan,and (3) Black with Tan belly × Agouti F₁s are all agouti.If you were to cross the F₁s from (1) with the F₁s from (2) ,what proportion of the resulting offspring would you expect to be black with a tan belly?

A) None
B) $\frac { 1 } { 4 }$
C) $\frac { 3 } { 16 }$
D) $\frac { 1 } { 2 }$
E) $\frac { 1 } { 16 }$
