You may be curious to know what the color of your future child’s eyes will look like.
After extensive research, and examining millions of couples, the scientists concluded that there was an interesting relationship between the color of the parent’s eyes and the color of their baby’s eyes.
The effect of genes on the color of the child’s eyes
Understanding how eyes get their color and the role genetics play can take some of the mystery out of this phenomenon.
Scientists once believed eye color was determined by a single gene, but advances in genetic research and genomic mapping have revealed that more than a dozen genes influence eye color. (1)
What determines the color of the 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 (denote by two capital letters, BB), and heterozygous means that the two copies of the gene differ or are recessive (denote by two small letters, bb). - Dominant Eye Color
Brown and green are dominant eye colors. There is a 75 to 95% chance of the baby getting brown or green eyes if both the parents have the same colored eyes. - Recessive Eye Color
Blue is recessive eye color. It’s highly unlikely for a baby to have blue eyes if both the parents have brown eyes. - Genotype
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. - Phenotype
The phenotype is the physical appearance of the genotype, which in this case is the eye color. (2)
