In cats, gene 1 specifies coat color; allele B leads to black coat while allele b leads to chocolate coat color. Gene 2 can inhibit coat color: genotype cc leads to an albino cat while at least one copy of allele C allows the full color from gene 1 to be expressed. From the cross bbCc x BbCc, what fraction of the offspring are expected to be albino?

a. 8/16

b. 1/16

c. 4/16

d. 2/16

e. 3/16
