In cases of incomplete dominance, the phenotype of the offspring is a blend of the phenotypes of the parents. When a black chicken (BB) is crossed with a white chicken (WW), the resulting offspring would display an intermediate phenotype.
Given that BB represents black and WW represents white, the offspring from this cross would show a phenotype that is a mixture of both, resulting in the color gray.
Therefore, the expected phenotype of the offspring is:
**D: All gray**.
