in mouse, black fur (B) is dominant to brown fur (b), and short tail (T) is dominant to long tail (t). The two genes are on different chromosomes.

in mouse, black fur (B) is dominant to brown fur (b), and short tail (T) is dominant to long tail (t). The two genes are on different chromosomes. If a black and short-tailed mouse is crossed with a brown and long-tailed mouse, what fraction of the progeny will be black and short tailed?

(A)100%

(B)50%

(C)75%

(D)25%

(E) It depends on the first mouse genotype
