Cat fur color is determined by codominance. The allele for tan fur (TT) and the allele for black fur (BB) are codominant. The heterozygous condition (TB) results in a cat with tan and black spots, called a tabby cat.
If a tan cat was crossed with a tabby cat what are the chances of a tan cat? What are the chances of a black cat?

Sickle cell anemia is a trait that exhibits codominance. A person with an AA genotype does not have sickle cell anemia, and a person with an SS genotype has full sickle cell anemia. A person with an AS genotype will have some sickle-cells, though s/he might show minimal or no symptoms (a “carrier”).
Englebert is a carrier for sickle-cell anemia (shows minimal symptoms), and his wife, Gwendoline, does not have it. What are the chances that Engelbert and Gwendoline will have a child with ANY sickle-shaped blood cells?
