When both parents have blue eyes, the odds are 100%. But, if both parents have blue eyes or green eyes, the odds are a lot higher.

Green eyes + blue eyes= green eyes or blue eyes Green eyes + green eyes = green eyes or blue eyes Hazel eyes + blue eyes = hazel eyes, green eyes, or blue eyes Hazel eyes + green eyes = hazel eyes, green eyes, or blue eyes Hazel eyes + hazel eyes = hazel eyes, green eyes, or blue eyes Predicting Your Baby's EyesĪ more realistic look at eye colors offers the following possible combinations:īrown eyes + brown eyes = brown eyes, hazel eyes, green eyes, or blue eyesīrown eyes + hazel eyes = brown eyes, hazel eyes, green eyes, or blue eyesīrown eyes + green eyes = brown eyes, hazel eyes, green eyes, or blue eyesīrown eyes + blue eyes = brown eyes, hazel eyes, green eyes, or blue eyes Hazel eyes and green eyes present with specific amounts of melanin, less than what would present as brown eyes. Parents with brown eyes may give birth to children with dark brown eyes, light brown eyes, hazel eyes, green eyes, or blue eyes. Eyes come in different colors other than just brown and blue, because eye color is controlled by how much melanin we produce. The genetics of eye color is more complicated than just dominant and recessive genes. Taking a Deeper Look at Eye Color Possibilities More produces green eyes, more than that produces hazel eyes, and even more produces brown eyes, which is the most common eye color worldwide. The least amount of melanin produces blue eyes. There are many different eye colors, existing along a continuum. This accounts for differences in eye color. While everyone generally has roughly the same number of melanocytes, how much melanin they produce differs widely from person to person. Special cells called melanocytes produce melanin. Eye color depends on how much melanin is stored in the iris. Melanin is the pigment that colors the human body. The exact color of your baby’s eyes depends on how much melanin he produces, which is controlled by the genetic code in our chromosomes. People generally have brown eyes, hazel eyes, green eyes, or blue eyes. This is the same reason that the sky and the ocean appear blue. When light scatters, the longest wavelengths are blue, so that is what we see. Melanin is brown, and little to no melanin makes the eye color appear blue. Varying levels of melanin are responsible for eye color. There is no blue pigment in the human iris or anywhere in the human body. Interestingly, blue eyes only appear that way. Ocular albinism can produce blue eyes in people with dark hair color and dark skin color. This ancestor most likely lived close to the Baltic Sea between six and ten thousand years ago and underwent a mutation that left them born with different genes.Īlbinism may also be responsible for blue eye color. The genetic mutation behind blue eyes, called Herc2, actually switches off the gene that colors brown eyes, and leaves them blue.Įveryone with blue eyes is related to a single, common ancestor.
