In mice, coat color is determined by two genes:

B: Black coat (dominant), b: brown coat (recessive).

C: Pigment expressed (dominant), c: no pigment (albino, epistatic to B/b).

A cross between two heterozygous mice (BbCc × BbCc) produces the following Punnett square:

What is the probability of producing a brown-coated mouse that is not albino?
