Answer: The expected ratio would be 1:2:1.
Explanation: In a dihybrid cross, an organism with two different characteristics crosses with another organism with other two different characteristics. In this question, for example, the doubly heterozygous agouti mouse is represented by AaBb and the doubly homozygous recessive white mouse is aabb. So crossing them, we'll have
ab
AB AaBb (agouti)
Ab Aabb (black fur)
aB aaBb (albino)
ab aabb (albino)
Analising the table, there is 1 in 4 chances of a agouti; 1 in 4 chances of a black fur and 1 in 2 chances of an albino, therefore, the ratio is 1:2:1.
Having no antigens is type O blood, which is what makes it a universal donor (It doesn't react violently with other blood types)
