If two brown-eyed people have a blue-eyed child, we can deduce which of the following? A. The gene for blue eyes is sex-linked. B. The gene for blue eyes is recessive. C. The child's eye color is the result of mutation. D. The gene for brown eyes is recessive
The correct answer is B. Brown eyes are dominant. Each parent has a brown gene and a blue gene. Their child got the blue gene from each parent and has two blue genes which is the only way recessive genes are phenotypically expressed.
