The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.
A couple's children can have almost any eye color, even if it does not match those of either parent. Currently it is thought that eye color is determined by about six genes, so you can imagine how inheritance of eye color becomes very complicated.
For two parents with brown eyes to have a blue-eyed child, both parents must genetically be Bb. When this happens, there is a 1 in 4 chance that these parents will have a bb child with blue eyes.
Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
Both parents with green eyes: 75% chance of baby with green eyes, 25% of baby with blue eyes, 0% chance of baby with brown eyes. One parent with brown eyes and one parent with blue eyes: 50% chance of baby with brown eyes, 50% chance of baby with blue eyes, 0% chance of baby with green eyes.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
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.
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.
In concluding the study, co-author and psychologist at the University of Padova in Italy Paola Bressan noted that to the best of her knowledge, “no study has either replicated or supported” the findings from the 1995 study that stated babies resemble their fathers.
If one biological parent has blue eyes and the other brown, then your child has a 50-50 chance of having permanently blue eyes. If both biological parents have blue eyes, then it's very likely that your child's eyes will be permanently blue.
Two brown-eyed parents: Odds are that the baby will have brown eyes, but if either or both parents have family members with blue or lighter-shade eyes, there is a chance that the baby could have an eye color other than brown.
The inheritance of eye color is more complex than originally suspected because multiple genes are involved. While a child's eye color can often be predicted by the eye colors of his or her parents and other relatives, genetic variations sometimes produce unexpected results.
Some seemingly impossible genetics can and do happen sometimes. This means that your kids might get your grandparent's darker eyes or hair even if you have kids with someone with blonde hair and blue eyes. It just would be much less likely than blonde haired, blue eyed kids.
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.
Did Elizabeth Taylor have violet eyes? These days, thanks to colored contact lenses, anyone can have violet-colored eyes . Taylor didn't come by her purple peepers that way; the first tinted contact lenses weren't commercially available until 1983. Taylor's eye color was the real deal.
Australian cricketer Shane Warne had complete heterochromia: his left eye was green and right eye was blue. Professional baseball pitcher Max Scherzer has complete heterochromia: his right eye is blue and his left eye is brown.
And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
Genetically, a person actually carries more of his/her mother's genes than his/her father's. The reason is little organelles that live within cells, the? mitochondria, which are only received from a mother. Mitochondria is the powerhouse of the cell and is inherited from the mother.

The myth stops here
And while we have the least amount when we enter the world for the first time, remember that babies may be born with eyes of blue, brown, hazel, green, or some other color. It's simply a myth that all of us — or most of us, for that matter — are blue-eyed at birth.
If you have green eyes, you're in luck. In addition to being the rarest eye color among Americans, green eyes are the most attractive, according to 66,000 people who voted in our survey.
Originally, all humans had brown eyes. Some 6,000 to 10,000 years ago, a genetic mutation affecting one gene turned off the ability to produce enough melanin to color eyes brown causing blue eyes. This mutation arose in the OCA2 gene, the main gene responsible for determining eye color.
