Bird feathers, like human hair, have complex forms due to variation in protein structure. In domesticated birds, feathers may be straight or curled. Assume that feather type is determined by a single gene and that the allele for curled feathers is dominant over the allele for straight feathers. In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have curled feathers? A. 0%
B. 25%
C. 50%
D. 100%
