                                 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
