Answer:

here.

Explanation:

The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.

Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.

Crossing CB CB × CW CW,

100% CB CW - tan-coloured birds
