In the case of incomplete dominance, when a black chicken (BB) is crossed with a white chicken (WW), the resulting offspring will have a phenotype that is a mix of the two parental traits.
Given the incomplete dominance:
- The black chickens represented by "BB" will show a black phenotype.
- The white chickens represented by "WW" will show a white phenotype.
When crossed, the offspring (BW) would exhibit a phenotype that is intermediate between black and white, typically referred to as gray in this scenario.
Therefore, the expected phenotypes of the offspring would be **all gray** (option b).
