Codominance & Multiple Alleles

Chicken feathers are inherited through codominance. When a black chicken BB is mated with a white chicken WW, the resulting phenotype is called erminette/checkered BW.   

What are the phenotypes if a checkered /erminette chicken is mated with a black feathered chicken.

• Black: 50%

  White: 0%

  Checkered: 50%

• Black: 0%

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?

• 50%, 50%

• 50%, 0%
