If you and your partner both have blue eyes, your baby is highly likely to have blue eyes. If you and your partner both have brown eyes, your baby is highly likely to have brown eyes. If one of your baby's grandparents has blue eyes, your baby's chances of having blue eyes is higher.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
Permanent eye color is not set until a baby is at least 9 months old, so wait until your child's first birthday to determine what color they will be. Even then, sometimes you may find little surprises. Subtle color changes can still occur all the way up until about 6 years of age.
So really, any combination can result in a blue-eyed child, but only if there is blue eyes somewhere in one of the parents' ancestral lines. This is rare so blue eyes remain rare. But, if both parents have blue eyes or green eyes, the odds are a lot higher. When both parents have blue eyes, the odds are 100%.
If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation. However, since eye color is polygenic, several other genes exert their effects as well.
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
Do grandparents' eye color affect baby? Yes! Grandparents' eye color can also impact baby's eye color. Baby eye color is genetic, and genes pass from generation to generation.
What color will GRAY babies' eyes turn? If your child is born with gray eyes they may stay light or actually turn hazel or brown during the course of your child's first year of life.
Generally, changes in eye color go from light to dark. So if your child initially has blue eyes, their color may turn green, hazel, or brown. But if your baby is born with brown eyes, it is unlikely that they are going to become blue. It is impossible to predict a baby's eye color just by looking at the parents' eyes.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Genetics and Eye Color
You inherit one from the mother and one from the father. If the two alleles of a specific gene are different (heterozygous), the trait that is dominant is expressed (shown). The trait that is hidden is called recessive. Brown eye color is a dominant trait and blue eye color is a recessive trait.
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
If one of the grandparents has blue eyes, the odds of having a baby with blue eyes increases slightly. If one parent has brown eyes and the other has blue eyes, the chances of having a brown-eyed or blue-eyed baby are roughly even.
Eye color is determined by genetics and genes can vary between siblings. We all have genes in our body, and our genes carry DNA. Our DNA controls the way that we express different characteristics in our body, everything from hair color to eye color to skin color.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
Blue eyes. This is the next most common eye color, encompassing about 10% of the population. While blue eyes are more sensitive to light during the day, people with blue eyes tend to see better at night – unless there are bright lights.
Unfortunately, unless you were born with blue eyes, there aren't any ways to naturally change your eye color.
Blue Eyes are More Sensitive to Light
Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible “blue” light from sunlight and artificial sources of these rays.
Did Elizabeth Taylor Really Have Purple Eyes? This is a popular myth. Elizabeth Taylor's eyes appeared purple in some photos due to lighting, makeup, and clothing. In reality, her eyes were blue, which can be seen in the vast majority of her photos.
