It is not possible for two brown eyes to make blue. Eye color is determined by the amount and type of pigments within the eye’s iris. Brown eyes have a lot of melanin, which is a type of pigment that gives eyes a brown color.
Blue eyes have a minimal amount of melanin and the other type of pigment, called lipochrome, is what gives the eyes a blue color. Therefore, two brown eyes cannot make blue because they do not have the right combination of pigments needed to do so.

Can 2 brown eyes make a blue-eyed baby?
No, it is not possible for two brown-eyed parents to produce a blue-eyed baby. Eye color is determined by a combination of genetics passed down from both parents. Brown eyes are a dominant eye color, meaning that a baby will always have brown eyes if both parents have brown eyes.
To get a blue-eyed baby, one parent would need to either have blue eyes or carry the recessive gene for blue eyes. A blue-eyed parent can pass a blue-eyed gene along to their baby, but two brown-eyed parents cannot create a blue-eyed child without outside help.
Which parent determines eye color?
Eye color is determined by both parents. A baby’s eye color is determined by the amount and type of pigmentation in the iris. Each parent passes one of two types of genes which are either dominant or recessive.
Dominant genes are always expressed while recessive genes may or may not be expressed. Depending on which type of gene each parent passes to the child, the genes will interact with each other to determine the baby’s eye color.
Generally, the most dominant gene will be expressed, however, with some mixing of dominant and recessive genes this can vary greatly for each individual. For example, if both parents have a dominant gene for brown eyes, the baby is likely to have brown eyes.
However, if one parent has a dominant blue eye gene and the other a brown, their baby’s eye color could range from blue to green to brown, depending on the combination of genes the child inherits.
Can two parents with blue eyes have a child with any other eye color?
Yes, two parents with blue eyes can have a child with any other eye color. Eye color is determined by many factors that are inherited, not just the eye color of the parents. In fact, it is possible for parents to pass on different versions of their eye color gene to their child, resulting in a different eye color.
For example, if both parents have either a dominant or recessive blue eye color gene, but neither has a dominant brown eye color gene, their child can have brown eyes. This is because the brown eye color gene is dominant, so if either parent carries it, the child will have brown eyes.
Other eye colors, such as hazel and green, can occur when parents with blue eyes pass on a combination of different eye color genes to their child.
What’s the rarest eye color?
The rarest eye color is believed to be amber. Amber eyes can range in color from light yellowish-brown, to golden yellow or golden-green, to deep golden or black. Eyeshine in amber eyes reflects whatever color is near it, giving them a bright shimmer.
Amber eyes are noticeable, but very rare in humans. They are most common in parts of Asian, Southwest Asia, and Eastern Europe, though they can occur anywhere in the world.
How do babies get blue eyes?
Babies are born with blue eyes for a variety of reasons. First, the genetics of their parents may make them predisposed to having blue eyes. Blue eye color is an inherited trait that is passed from both parents, although if both parents have blue eyes, the baby is almost guaranteed to have blue eyes as well.
In addition, babies may appear to have blue eyes due to a lack of melanin in the iris. Melanin is a pigment that gives color to the eyes, and all babies are born without it. As the baby’s eyes become exposed to light, they begin to produce the pigment and the eye color then darkens.
This process can take up to a year, but some babies never reach their true eye color. Finally, medical conditions and trauma can also explain why a baby has blue eyes. Some genetic disorders, such as albinism, can lead to a baby having unusually light-colored eyes.
Similarly, if a baby is born prematurely, their eyes can be “stunted” and fail to darken further, resulting in blue eyes.
What color eyes can two blue-eyed parents have?
Two blue-eyed parents can have a child with any eye color as eye color is determined by a combination of several genes. Even though both parents may have blue eyes, they could still be carrying the genes for brown, green, or hazel eyes.
Therefore, a child of two blue-eyed parents could have blue eyes, brown eyes, green eyes, or hazel eyes. In fact, the child could even have a mix of two different eye colors. While it is possible for two blue-eyed parents to have a child with any eye color, it is more likely that the child will have blue eyes.
This is because if both parents carry the gene for blue eyes, it is more likely that the same gene will be passed onto the child. Even if the parents carry other eye color genes, the blue genes are more likely to be dominant.
What are the odds of two blue-eyed parents having a blue-eyed child?
The odds of two blue-eyed parents having a blue-eyed child is approximately 75%. Both parents must be carriers of the recessive gene for blue eyes, meaning that they each have one gene for blue eyes and one gene for a different eye color (like brown or green).
If both parents are carriers, then there is a 1 in 4 chance that the child will have blue eyes, since each parent has a 50% chance of passing on the gene for blue eyes. Therefore, the odds of two blue-eyed parents having a blue-eyed child is 75%.
Can a baby have blue eyes if one parent has blue and one has brown?
Yes, it is possible for a baby to have blue eyes if one parent has blue eyes and one has brown. This is because brown eyes are the most common eye color, but there are many different shades of brown and blue that can result from the combination of genes from both parents.
A baby’s eye color is determined by the amount of melanin (pigment) they inherit from each parent. If both parents have different amounts of melanin in their eyes, their baby has a greater chance of having blue eyes than a baby whose parents have the same shade of eye color.
Blue eyes are recessive, meaning that the brown-eyed parent must also be carrying a gene for blue eyes in order for the baby to inherit it. Therefore, if one parent has blue eyes and the other parent has brown eyes, there is a very good chance that the baby will have blue eyes.
What genes are inherited from father only?
Genes are inherited from both parents, but there are some genes that are only passed down from the father. These are known as Y-linked (or Y-chromosomal) genes. Examples of Y-linked genes include those that determine male sex and sperm production and male pattern baldness.
Y-linked traits are only found in males, as they are only inherited from fathers. Due to the fact that males only have one X and one Y chromosome, since this gene is only present on the Y chromosome, it can only be passed down from father to son.
Other examples of Y-linked genes include factor VIII, a blood clotting gene, and various other X-linked recessive conditions.
Is eye color inherited from the mother or father?
Eye color is a polygenic trait, meaning that several gene variants influencing eye color are inherited from both the mother and father. Studies have found that both the mother and father contribute to a child’s eye color.
Through the process known as Mendelian inheritance, a child’s eye color can be determined through a combination of the two parents’ eye colors.
Eye color can either be determined by a single gene called the Locus Intergenic Pigment-1 (LIP-1 gene), or it can be determined by multiple genes. Examples of polygenic traits that are inheritied from both the mother and father include height, skin tone, and eye color.
This means if both of your parents have brown eyes, there is a higher chance that you will have brown eyes than if one of your parents had green eyes.
In addition to the genes inherited from the mother and father, environmental influences have also been found to play a role in eye color. Studies suggest that environmental factors such as diet, sunlight exposure, and smoking during pregnancy can affect eye color in newborns.
While eye color is usually determined at birth, some studies suggest that eye color can change slightly as a person ages, again likely as a result of environmental factors.
Can babies get eye color from grandparents?
Yes, babies can inherit eye color from their grandparents. This is because eye color is determined by a combination of genetics and melanin production, and both of these factors can come into play when grandparents pass traits down to their grandchildren.
The exact eye color depends on a wide variety of factors, and it is often difficult to predict with certainty the exact shade of a child’s eyes. Factors such as parental eye color, environmental influences, and genetic mutations can all influence the color of a baby’s eyes.
However, research has shown that certain eye colors such as brown are often inherited from grandparents. Similarly, blue eyes are more likely to be inherited from grandparents, especially if both of the baby’s parents have brown eyes.
Ultimately, the exact eye color of a baby is determined by complex, individual genetic combinations, and so it is impossible to predict with certainty what a baby’s eye color will be.
What makes hazel eyes?
Hazel eyes are caused by the amount and mixture of melanin in the iris. Hazel eyes usually contain flecks of gold, green, brown, and other colors. They may have a multi-colored, rippled, or textured appearance, which may be surrounded by a dark or light halo.
It usually takes a combination of several or many different colors for them to be labeled as hazel. The amount of melanin and the combination of colors vary from person to person, meaning no two hazel eyes are exactly alike.
Most importantly, this trait is hereditary, so if you have family members with hazel eyes, then you may have a higher likelihood of having them too.
Why are green eyes so rare?
Green eyes are so rare because of their low prevalence in our ancestry. Most people have a mutation called OCA2, which leads to the brown pigment in the eyes. Green eyes are the result of a completely different mutation in the HERC2 gene that leads to the yellow/green pigment in the eyes.
This mutation has been passed down from generation to generation, but because it has such a low prevalence, it has remained rare. Higher concentrations of green eyes appear in populations of Northern and Central Europe, while it is rare to see green eyes in other parts of the world, such as Asia and Africa.
Additionally, the green eye gene is recessive, which means if someone has the gene but their partner doesn’t, there is a lower chance of the couple having a green-eyed child. For this reason, green eyes may remain rare and somewhat mysterious.
What color eyes will a child have if both parents have blue eyes?
If both parents have blue eyes, their child will likely have blue eyes as well. This is because eye color is an inheritable trait, meaning that the genetic material (DNA) which is passed down from each parent will likely result in the same eye color.
However, it is possible that a child can have a different eye color than their parents, as different alleles (alternative forms of a gene) may be present and expressed. Depending on the combination of alleles, other eye colors such as hazel, green, or brown could arise.
