Inheritance and genetic crosses

Some inherited traits are determined by alleles that show codominance.

In a certain breed of chickens, the allele for black feathers ( $F^B$ ) is codominant with the allele for white feathers ( $F^W$ ).

A heterozygous chicken ( $F^B F^W$ ) has blue-grey feathers.

Give the genotype of a chicken with black feathers.
