Eye Color of Offspring Can Differ from Parents

Dear Dr. Dave and Dr. Dee,

Is it possible for two people with brown eyes to have one child with blue eyes and another with brown eyes?

Signed,

Dear Suspicious,

Yes, it is possible for two brown-eyed parents to have a child with blue eyes. If both brown-eyed parents carry the recessive gene for blue eyes, then their offspring would be expected to have approximately a 25% chance of having blue eyes.
