True breeding agouti mice with genotype AABB were cross to true breeding albino mice with genotype aabb. All F1 offspring having agouti phenotype were allowed to intercross to produce F2 progeny as following 

                                 A- B -          agouti,

                                 aa B-            black

                                 --  bb            albino

Following genetic cross and there proportional?

Genetic cross	Proportional of albino
AaBbXAaBb	A
AaBb X aabb	B
Aabb X aaBb	C
AABbX aaBb	D
