Genetics Review Problems Monohybrid Cross A male and female flamingo are deciding whether or not to have kids. The father knows that to be able to balance (B) on one leg, a child must contain the dominant B allele in its genotype. He also knows that if a bis inherited, the baby flamingo would be unbalanced (b) on one leg. If both parents are heterozygous, what is the chance that they will have an "unbalanced" kid? 25% BB B b Genotypic Ratio: 25% 65 50% Bb Phenotypic Ratio: 756 beland Chance: 25 256 wrbalenard b Bb bb Dihybrid Cross R = normal runner B = Black hair runs only in circles b=brown hair Cross a heterozygous normal running, heterozygous black mouse with a homozygous normal running. homozygous black mouss. a.

Horses with the D1D1 genotype are white colored, horses with the D1D2 genotype are white and black spotted, and horses with the D2D2 genotype are black in color.
