Question

If a black chicken (BB) is crossed with a white chicken (WW) and incomplete dominance is observed, what are the expected phenotypes of the offspring? (1 point)
All black
All gray
• All white
All red

In cattle, coat color is controlled by codominant alleles. A red-coated cow (RR) is crossed with a white-coated bull (WW). What are the expected phenotypes of the offspring? (1 point)
All red coat
All pink coat
Red and white coat
All white coat

Answer 1

1) All gray — incomplete dominance gives BW heterozygotes an intermediate (gray) phenotype.
2) Red and white coat — codominance gives RW heterozygotes expressing both colors (e.g., roan).
