Mary and Zeke have three children, all of whom have blue eyes. However, both Mary and Zeke have brown eyes. Using genetic principles, explain the probability of this situation occurring
What will be an ideal response?
Answer will include that Mary and Zeke must each have a dominant gene for brown eyes, since they both have brown eyes, and both of them must also have a recessive blue-eyed gene. The dominant brown-eyed gene masked the recessive, so both parents have brown eyes. Every time they conceive a child, there will be a one in four chance of their two recessive genes pairing up and producing a blue-eyed child.
