Question

Traditionally, blue-eye color is considered recessive to brown eyes in humans although, as noted in the chapter, eye color in humans is not a single gene trait. It has occasionally been the subject of folklore and “common knowledge” that blue-eyed parents usually have blue-eyed offspring. However, blue-eyed parents do often have brown-eyed children. In addition, when one brown-eyed child is born in this family, it is expected that subsequent children will also have brown eyes. Assuming the blue eyes really is recessive to brown eyes for any single gene being tested, how can you explain this result? Be sure to use the correct terminology.
