If both of you have brown eyes, then there is generally a 25% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1% chance of the baby having blue eyes.
Is it possible for two brown eyed parents to have a blue eyed baby?
Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. However, since eye color is polygenic, several other genes exert their effects as well. So yes, while it’s unusual, it is possible for blue-eyed parents to have a brown-eyed child!
What will my baby’s eye color be?
Most babies of Caucasian origin have dark blue eyes when born. However, the original color, be it brown, green, blue or hazel, will be determined over time. The child will get the actual eye color with exposure to light, and it depends on the amount and diffraction of light.
