Answer:
10 (agouti) : 3 (black) : 3 (white)
Explanation:
Genotype AaBb can produce gametes AB, Ab, aB, ab.
The cross between Aa Bb × Aa Bb:
The phenotype ratio is 10 (agouti) : 3 (black) : 3 (white)
Genotypes for the agouti phenotype are: AABB, AABb, AaBB, AaBb
Genotypes for the black phenotype are: AAbb and Aabb
Genotypes for the white phenotype are: aaBB, aaBb and aabb
