A babys eye color is determined by the combination of the eye colors of the parents and whether the genes are dominant or recessive. Eye color traits are influenced not only by one gene but by various genes, making it difficult to predict the exact eye color of a baby. However, there are some general rules that can be followed:

• Brown and green eyes are considered dominant, while blue eyes are recessive.
• If both parents have brown eyes, there is generally a 25% chance that the baby will have blue eyes if both parents carry the recessive blue-eye gene.
• If one parent has a recessive blue-eye gene and the other has two brown, dominant genes, there is a less than 1% chance of the baby having blue eyes.
• It is possible for blue-eyed parents to have a brown-eyed child, and even two brown-eyed parents can make a blue-eyed baby because there are no full 100 percent definite rules.

It is also important to note that the inheritance of eye color is polygenic, meaning that eye color traits are influenced not only by one gene but by various genes. Therefore, it is difficult to predict the exact eye color of a baby.
