Two Andalusian chickens are crossed to produce offspring. One parent has black feathers, and the other parent has white feathers. In this type of chicken, feather color is a trait that exhibits incomplete dominance.Which statement is most likely correct about the offspring?
Answer
A
All the chicks will have both black and white feathers.
B
Some chicks will have only black feathers and others will have only gray feathers.
C
All the chicks will have only black feathers.
D
All the chicks will have only gray feathers.
Explanation
With incomplete dominance, a chicken with one black-feather allele and one white-feather allele has an intermediate gray color. Crossing a black-feathered parent with a white-feathered parent gives every chick one allele from each parent, so all the chicks will have only gray feathers.
