Can two parents with blue eyes have a child with brown eyes? Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter.
Both parents with blue eyes: 99% chance of baby with blue eyes, 1% chance of baby with green eyes, 0% chance of baby with brown eyes. 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.
If both parents have blue eyes, the children will have blue eyes. If both parents have brown eyes, a quarter of the children will have blue eyes, and three quarters will have brown eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
She has blue eyes because of A but carries a brown eye gene B. To make things simpler, we'll say her blue-eyed husband John is aa bb. For Jane to have a brown-eyed child, she just needs to pass both her a and her B to her child. Now her child will be aa Bb … the child will have brown eyes even with blue-eyed parents.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
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.
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.
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.
Brown Eyes: 45 percent. Blue Eyes: 27 percent. Hazel Eyes: 18 percent (Note: Hazel eyes consist of shades of brown and green.)
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.
Brown and green alleles will always out-rule blue alleles, with brown being the most dominant. Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes.
Generally, darker colors are the dominant traits, while lighter colors are recessive, so a person with one brown-eyed gene and one blue-eyed gene will have brown eyes. 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.
Only 8 Percent of the World's Population Has Blue Eyes
Since blue eyes are genetically recessive, only 8 percent of the world's population has blue eyes. While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount of melanin in the front layers of the iris.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
A blue and a green-eyed parent will have all hazel-eyed kids. This is one of the reasons I like the modifier gene explanation so much. It can help explain how green and blue-eyed parents might have hazel-eyed kids.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
The vast majority of people in the world have brown eyes. The second most common color is blue, but people can also have green, gray, amber, or red eyes.
What ethnicity has hazel eyes? Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent.
Blue eyes are rare, making up just 8-10% of the world's population. Blue eyes are caused by a relative lack of melanin in the iris. Just like your skin and hair, how much melanin you have determines your eye color. All eyes are technically brown because melanin itself is brown.
Let's look at why a blue-eyed parent (dad) and a brown-eyed parent (mum) and can have brown, green, and blue-eyed children. For gene 1, OCA2, there are two possibilities: brown or blue. The brown version of gene 1 is dominant over the blue one.
Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes. Eye color is very complicated and involves many genes.
Genes from your parents, grandparents and other relatives determine what color your irises will be. These genes also play a role in the color of your hair and skin.
If, say, my wife was also blonde and blue-eyed, would it somehow lessen the chances of our children being blonde and blue-eyed? Yes, grandparents' genes can affect how their grandchildren look.
As a general rule of thumb, your height can be predicted based on how tall your parents are. If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren't the sole predictor of a person's height.
