In incomplete dominance, the alleles do not exhibit a complete dominant-recessive relationship; instead, the heterozygous phenotype is a blend of the two homozygous phenotypes.
In this case, if we have a black chicken represented by the genotype BB and a white chicken represented by the genotype WW, the offspring (all BW) would exhibit a phenotype that is a mix of both black and white.
Typically, if black is one extreme (BB) and white is another (WW), then the expected phenotype of the offspring (BW) would be a gray or light-colored chicken, which is a blend of black and white feathers.
Therefore, the expected phenotype of the offspring would be gray chickens.
