Question

Mating

AaBb x AaBb produces what genotypic and phenotypic ratios in the offspring?

Answer 1

gamete AB Ab aB ab

AB AABB AABb AaBB AaBb

Ab AABb AAbb AaBb Aabb

aB AaBB AaBb aaBB aaBb

ab AaBb Aabb aaBb aabb

Genotype ratio

AABB 1 AaBB 2. aaBB. 1

AABb 2. AaBb 4. aaBb 2.

AAbb 1. Aabb. 2. aabb 1

Phenotypic ratio if A dominant a and B dominant to b

9 A B phenotype

3 A b phenotype

3 a B phenotype

1 a b phenotype
