Yes, 2 brown eyes can make a brown eyed baby! This is because both the parents carry two “brown eye” genes, which when combined can result in a brown eyed baby. While it is possible to predict the eye colors of children based on those of the parents, it’s not always exact and there can be many other factors at play.
Both parents must carry a dominant “brown eye” gene for a brown eyed baby to be produced. If only one parent carries a dominant brown eye gene, then the baby has a 50/50 chance of having brown eyes. It is also possible for brown-eyed parents to produce a blue-eyed baby if both parents also carry a recessive blue eye gene.

What happens if both parents have brown eyes?
If both parents have brown eyes, then it’s most likely that their child will have brown eyes as well. This is because the gene responsible for brown eyes, known as the “brown eye gene”, is a dominant gene.
This means that the trait associated with the brown eye gene (in this case brown eyes) will be expressed in the offspring if just one parent has the gene. This is why two parents who both have brown eyes will end up having a child with brown eyes.
However, it is still possible for the child to end up with blue eyes, as both parents could possess the recessive gene linked to blue eyes – this is known as a “recessive gene pair”. In this case, even though both parents have brown eyes, if they have the recessive gene pair, then the child has a 25% chance of being born with blue eyes.
Can 2 brown eyed parents produce a blue eyed child?
Yes, it is possible for two brown-eyed parents to produce a blue-eyed child. This occurs due to inheritance and the principle of dominance. Eye color is determined by two genes—one from each parent.
The brown eye gene is dominant and the blue eye gene is recessive. Therefore, if one parent passes along a dominant brown eye gene, and the other parent passes along a recessive blue eye gene, their offspring will be born with blue eyes.
The phenomenon of two brown-eyed parents producing a blue-eyed child is commonly referred to as a genetic anomaly or mutation. This mutation is more common in certain populations, such as those with Celtic ancestors, compared to those of Asian or African descent.
Keep in mind that even if two brown-eyed parents produce a blue-eyed child, this doesn’t guarantee that their other children will be born with blue eyes. If one or both of the parents carries the recessive blue eye gene, their offspring still has a chance of inheriting blue eyes, but it’s not guaranteed.
It is important to note that when both parents carry the recessive blue eye gene, the odds of producing a blue-eyed child increase significantly. In the end, it all comes down to the combination of genes passed down from the parents.
Can a baby have brown eyes If both parents have colored eyes?
Yes, it is possible for a baby to have brown eyes even if both parents have colored eyes. This is because eye color is determined by genetic coding, and a single gene may hold two or more different variations.
Thus, each parent may carry a dominant or recessive gene for eye color, and a baby can receive one from each parent, resulting in a combination of eye colors that may not match either parent. Additionally, some studies suggest that eye color is actually determined by a combination of several genes, making it even more likely that a baby can have a unique eye color compared to its parents.
What are the chances of two brown eyed parents make blue?
The chances of two brown-eyed parents making a blue-eyed child are relatively low, but not impossible. There is a strong genetic component that determines eye color, and parents can pass along different versions of genes for eye color to their children.
Brown is the most dominant eye color, so for a blue-eyed child to be born, both parents must carry and pass along the recessive gene for blue eyes. However, if one parent is heterozygous for eye color (they carry both dominant and recessive genes for brown and blue eyes, respectively), then there is a 25% chance that their child will have blue eyes.
Additionally, while the majority of cases of blue eyes are due to people having a recessive gene, some non-brown eyes can be attributed to mutations in the genes that control eye color. While the chances of two brown-eyed parents having a blue-eyed child are low, it is not impossible.
What’s the rarest eye color?
The rarest eye color is green. Only 2 percent of the world’s population has green eyes. While many people believe that blue is the rarest eye color, green eyes are actually far rarer. Green eyes are a result of low levels of melanin in the iris and often occur in people of European descent, although they can also occur in those of African or Asian descent.
The absence of melanin gives green eyes the unique color, but also makes them especially sensitive to light.
Which parent determines eye color?
Both parents have a role in determining the eye color of their offspring. Eye color is a polygenic trait, meaning it is determined by the combination of several different gene pairs. A single gene can’t determine eye color.
A baby’s eye color is usually determined by the combination of their parent’s genetic code. Eye color is determined by the amount and type of melanin in the iris of the eye. About 80-90% of a baby’s eye color is determined by the two eyes of their parents.
The eye color of the parent with the lighter eyes tends to dominate the baby’s eye color.
Brown is the most dominant eye color, while blue is the least dominant. If both parents have brown eyes, then their baby is almost certain to have brown eyes. If both parents have blue eyes, then the baby has a higher chance of having blue eyes.
However, if one has blue and one has brown, the baby may have either.
Eye color can also be influenced by other genetic factors, such as ethnicity and genetics from grandparents and other family members. Eye color is also impacted by hormones, such as those produced during pregnancy and during puberty.
All in all, many different factors work together to ultimately determine the eye size and color of an individual.
How is eye color passed down?
Eye color is determined by variations in gene expression and the presence of certain pigments. Eye color is a polygenic trait, meaning that several different genes play a role in genetically determining one’s eye color.
In particular, two genes, OCA2 and HERC2, are known to have the greatest effect on eye color. OCA2 plays a role in the production of melanin, the pigment with the greatest effect on eye color, and HERC2 determines how much melanin is produced.
Generally, a combination of multiple genes and environmental factors dictates one’s eye color. In terms of genetics, the combination of various alleles of the HERC2 and OCA2 genes produce different shades of eye color.
For example, two HERC2 alleles on chromosome 15 determine if a person has brown eyes, while two different HERC2 alleles result in blue eyes. Generally speaking, blue eyes are associated with lower amounts of melanin, while brown eyes are associated with higher amounts.
However, there are many shades of eye color that can be produced from the same combination of alleles.
Therefore, eye color is passed down from one generation to the next through genetic inheritance of the alleles at the HERC2 and OCA2 loci. Each person inherits two alleles for each gene locus from their parents, one from the father and one from the mother.
Depending on the combination of alleles received, eye color will vary. So there is usually some variation in eye color from generation to generation.
What genes are inherited from father only?
A number of genes are inherited exclusively from a father and not the mother. These genes are known as paternally inherited genes, and they are present in the form of a Y-chromosome. The Y-chromosome is only present in males and determines the male sex.
It regulates the expression of other genes, some of which are not present in a female’s genome. Some of the paternally inherited genes from a father include the genes that regulate male sexual development, height, hair color, eye color, proneness to certain diseases, familial facial features and inherited personality traits.
An important paternally inherited gene is the one that causes Huntington’s disease, a debilitating disorder that affects a person’s movement, behavior and cognitive abilities. Additionally, due to the presence of a Y-chromosome, a female inherits some of the father’s mitochondrial DNA (mtDNA).
Mitochondrial DNA is thought to be passed on through the female line only; however, males can also pass mtDNA on to their offspring.
What color will baby’s eyes be if Mom has blue and Dad has brown?
It is impossible to know exactly what color a baby’s eyes will be before they are born, as the color is determined by a range of genetic factors related to both parents’ eye color. Although a baby’s eye color is usually the same as one of their parents (if both parents have blue eyes, for example, it is likely that the baby will have blue eyes too), it is possible for the baby to have an eye color that is a mix of both of the parents, or even an entirely different color altogether.
In the case of a baby with one brown-eyed parent and one blue-eyed parent, the baby may possess eyes that are a shade of brown leaning towards blue, a more muted green, or even a light gray. The baby’s eye color may change over the first few years of life, but it will usually stabilize around the age of three.
How can a baby have different eye colors from both parents?
A baby can have different eye colors from both parents due to genetics. Eye color is determined by the presence or absence of a certain pigment called melanin. Any individual may have two copies of the same eye color gene or two different ones, which is genetically inherited from each parent.
Since there are multiple combinations of eye color genes, one or both of the baby’s parents could have a different combination from the baby. In addition, the color present in one parent may be more dominant than the other.
This is why it is possible for a baby to have different eye colors from both parents.
Why do both my parents have brown eyes but I have blue eyes?
It is possible for both of your parents to have brown eyes and for you to have blue eyes due to genetic inheritance. Everyone carries two copies of every gene or DNA, one from each parent. Most of the genes that determine eye color can be seen in two ways – brown and blue.
If both of your parents have the same eye color, both of their gene combinations for eye color would be the same (i. e. both brown). However, when those genetically inherited genes are passed on to you, you may end up with a combination that includes both brown and blue genes, thus resulting in blue eyes even though both of your parents have brown eyes.
This is due to the concept of genetic recombination, which is when parts of our DNA are randomly shuffled around when making sperm and eggs. This means that our genetic material ends up randomly arranged and this can cause you to have traits that your parents don’t.
Is brown eyes dominant or recessive?
It depends on the specific gene responsible for the color of the eyes. The gene that determines brown eyes is an autosomal dominant gene, which means that only one gene is required for the trait to be expressed.
Studies have shown that the gene for brown eyes is more dominant than the gene for blue eyes. On the other hand, the gene for blue eyes is a recessive gene, which means that two copies of the gene are required for it to be expressed.
Therefore, brown eyes are more likely to be dominant over blue eyes.
Did Elizabeth Taylor have purple eyes?
No, Elizabeth Taylor did not have purple eyes. She was known for her captivating beauty and blue-violet eyes. Taylor’s eyes were often described as a “unique” or “unusual” shade of blue-violet. However, some sources allege that her left eye may have sometimes appeared a slightly deeper shade of blue, making it appear that her eyes were two different colors.
There is also speculation that her blue-violet eyes were actually the result of colored contact lenses, as Taylor was known to frequently wear them. Therefore, though she had very beautiful and captivating eyes, they were not purple.
Are GREY eyes the rarest?
No, grey eyes are not the rarest eye color. Brown eyes are the most common eye color, with more than half of the world population having brown eyes. Blue eyes are the second-most common eye color, and they have been found in many parts of the world.
Green eyes are the third-most common eye color and they are generally found in Northern and Central Europe. Grey eyes are the fourth-most common eye color, with less than 10% of the world’s population having them.
Grey eyes may be less common than other eye colors, but they still make up a substantial majority of the human population.
