If you have just had a child or are expecting one, you must have at least once wondered what color your child’s eyes would be. Whose eyes will your baby inherit - mother or father?
Well, you don’t have to wonder about it anymore. Our baby eye color calculator will give you a hint about what color eyes will soon be gazing at you. Try it out below!
Eye color is a physical trait determined by the pairing of genes from both the parents. The baby inherits 50% of eye color genetics material from each of its parents. Genes mutate to give alternative forms called alleles, and each allele slightly differs from the other. There are three pairs of alleles responsible for eye color with each allele giving either brown, green or blue. The brown allele is dominant over green and blue; green is dominant over blue and blue is recessive.
The newborn's eye color depends on both the parents' eye color and whether the alleles are dominant or recessive. The child may get two dominant alleles from the parents, one dominant one recessive or two recessive alleles.
Most of the babies born with blue eyes because the newborns take time for producing the pigment melanin.You cannot determine the exact color of the baby’s eyes until he or she turns three.
A baby eye color calculator is an online calculator that can help parents predict the eye color of their children. It tells the likelihood of the baby’s eye color on the basis of eye color genetics using color of the parents’ eyes.
Homozygous And Heterozygous:
Human beings have two copies of every gene. One is inherited from the mother, and the other from the father. Homozygous means that two copies match or are dominant (denoted by two capital letters such BB) and heterozygous means that the two copies of the gene differ or recessive (denoted by two small letters, bb).
Dominant Eye Color:
Brown and green are dominant eye colors. There is 75 to 95% chance of the baby getting brown or green eyes if both the parents have same colored eyes.
Recessive Eye Color:
Blue is a recessive eye color. It’s highly unlikely for a baby to have blue eyes if both the parents have brown eyes.
The genotype is the gene combination for a given trait, which, in this case, is the eye color. The mother and father’s genotype will determine the eye color of the children.
The phenotype is the physical appearance of the genotype, which in this case is the eye color.
If both the parents have blue eyes, there are 99% chances that the baby will have blue eyes.
If both the parents have brown eyes, there are 75% chances that the baby will have brown eyes.
If both the parents have green eyes, there are 99% chances that the baby will also have green eyes.
If both the parents have hazel eyes, there are 99% chances that the baby will also have hazel eyes.
The hazel eyes are still a mystery. The baby eye color calculator cannot accurately predict the likelihood of your child having hazel eyes, as this eye color is often a mixture of brown, green and amber hues.
Most of the new born babies have blue eyes, which may change color over time. The eyes remain blue if both the parents pass their recessive blue genes to the child. If this is not the case, the baby's eye color changes to permanent color (brown, green or any other color) as he/she ages. At the time of birth, there is a deficit of melanin pigment, but with time the iris starts producing melanin to give the eyes their actual color. It takes about six months to one year for the baby's actual eye color to surface.
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.
Likewise, Asian and African origin babies have brown or dark gray at the time of birth. They turn black or real brown over time.
Baby eye calculators are not entirely accurate as genes contribute to the eye color. Also, they do not explain hazel and other shades of brown. So we’d suggest you not to depend entirely on the calculator.
There are cases when babies are born with one eye as brown and another eye as blue. It is because of a medical condition called Waardenburg syndrome. However, this is a rare genetic disorder. In such cases, it is essential that you consult an ophthalmologist.
Studies are going on to find accurate reasons behind the changes in eye color of a newborn.
