The gene for blue eyes is an autosomal recessive trait, meaning that in order for someone to have blue eyes, both their parents must carry the gene. While many believe that blue eyes are a result of a combination of blonde hair and fair skin, this is not the case.
In reality, anyone can carry the gene for blue eyes regardless of their hair and skin color. Depending on their heritage, people of any ethnicity may carry the gene for blue eyes, though it is most common in Europeans and their descendants.
Thus, anyone can carry the gene for blue eyes; however, to express the trait both parents must pass it on.

Who does the blue eye gene come from?
The blue eye gene is actually a mutation located in the OCA2 gene (also known as the eye color gene) which produces a protein called the P-protein. This protein helps determine the melanin levels in the front layers of the eye and determines whether one has a blue, green, hazel, or brown eye color.
It is estimated to have originated somewhere between 6,000 and 10,000 years ago in the northwest part of the Black Sea region, around what is now modern day Turkey and the surrounding countries. Some scientists speculate that the blue eye gene began as a single mutation that became more widespread due to a process known as the founder effect, where a single population with a mutation (in this case, the blue eye gene) is isolated and the mutation is passed down over generations.
Another theory suggests that an individual with the blue eye gene may have had an advantage due to better eyesight in waters around the Baltic sea region, which could have lead to the mutation becoming more widespread.
Do blue eyes come from mother or father?
Whether blue eyes are inherited from the mother or father is a complicated answer, as although we understand genetics and have studied inheritance through Mendel’s work with pea plants, the exact nature of how traits such as eye colour are transmitted can still be somewhat of a mystery.
It is believed that the underlying cause of blue eye colour is the reduced amount of melanin, which needs to be activated in the iris, however, the actual mechanism of how this is carried out and which parents carry the genes is still unknown.
Whilst blue eyes do appear in both children and adults, it is generally understood that blue eye colour is only inherited from one of the parents. A child’s eye colour is determined at conception and is influenced by the genetic traits passed on from both parents, so although the mother’s eye and hair colour can play a part in determining the eye colour of the child, the father’s genes also contribute.
Scientists still don’t know if blue eyes are inherited primarily from the mother or father, although it is thought that they most likely come from both parents. To answer this question, it would require further scientific and genetic testing to fully understand the inheritance of the trait.
What parents make blue eyes?
Blue eyes are a common genetic trait that can be passed down from both parents. In order to have blue eyes, both parents must carry the recessive gene for blue eyes. If only one parent has the recessive gene, the child may still have blue eyes, but it is not likely.
In general, both parents must have the gene for blue eyes in order for the child to have them. It is also possible for two parents who both have blue eyes to have a child with brown eyes, as the gene for brown eyes is dominant.
Therefore, both parents must carry the gene for blue eyes in order to make blue eyes in a child.
Can two brown-eyed people have a blue-eyed child?
Yes, two brown-eyed people can have a blue-eyed child. This might seem surprising, but it is possible. This is because eye color is the result of a complex combination of genetics. Brown eyes are the most common eye color in humans, and blue eyes are recessive.
That means that in order for a child to have blue eyes, both parents must have the gene for blue eyes and both must pass them down.
Parents can have two different eye colors, and both can carry the recessive gene for blue eyes. Therefore, it is possible for two brown-eyed parents to have a blue-eyed child; however, the chances of this happening are lower than for two blue-eyed parents.
This is because the likelihood of both parents passing down the blue-eyed gene is lower if they both have brown eyes.
In some cases, two brown-eyed parents can have a blue-eyed child if a genetic mutation occurs. Mutations happen all the time, and they can bring about unexpected changes. If a mutation causes a baby to have a blue eye color, even though neither parent has the gene for it, then it is possible for two brown-eyed parents to have a blue-eyed child.
What genes are inherited from father only?
The genes that are inherited from a father only are known as Y-linked genes. These genes are located on the Y chromosome and are only found in males. Examples of these genes include genes involved in male fertility, male sexual development, and hair color.
Y-linked genes are passed on directly from father to son, and usually, do not undergo changes or mutations. However, certain inherited recessive genetic diseases found in males, such as congenital adrenal hyperplasia, are caused by mutations in Y-linked genes.
Interestingly, females can also carry certain Y-linked genes. This happens when a female receives an extra copy of the Y chromosome. These females typically have physical differences, such as taller stature and masculine physical features, and they may have infertility issues due to their extra Y chromosome.
In summary, Y-linked genes are inherited from the father and are only found in males. They can be associated with certain inherited recessive diseases in males, and females can sometimes carry Y-linked genes due to an extra copy of the Y chromosomes.
What makes a blue-eyed child?
A blue-eyed child is a child born with blue eyes, as opposed to other eye colors, like brown or green. This is caused by the inheritance of a recessive allele on chromosome 15. The recessive allele for blue eyes is the “e” gene, which is paired with a “b” gene from the other parent, resulting in the eye color blue.
Blue-eyed children can be found in any race or ethnicity. While it is impossible to tell from physical appearance whether a child has a recessive allele on chromosome 15, a blood test for the allele can be conducted to determine if the child has the blue eye gene.
Determining the genes a child inherited is also important for tracking familial health history and potential genetic disorders.
How can I make my baby’s eyes blue during pregnancy?
Eye color is determined by a combination of genetic factors, and the color that your baby’s eyes end up being is determined before you become pregnant. While some factors can influence the color of a baby’s eyes, it is impossible to definitively predict the color that they will be since it is largely determined by genetics.
Therefore, it is not possible to make your baby’s eyes blue during pregnancy.
To further elaborate, since eye color is determined by genetics, your baby could end up having the same eye color as either parent or it could end up being something completely different — both of which are completely normal.
If your baby ends up having a different eye color than either parent, that difference is likely due to other factors such as the genetic makeup of other family members or environmental factors that are out of your control.
If you do happen to be pregnant and are curious about what color your baby’s eyes might be, you can try having an ultrasound to gain more information, although eye color will not be certain until your baby is born.
Can kids get blue eyes from grandparents?
Yes, it is possible for a child to get blue eyes from their grandparents. The gene that determines eye color is passed down from each parent to their children. So, if both parents have the gene for blue eyes, it is likely that their children will also have blue eyes.
Additionally, if one or both of the parents have blue eyes and their parents have the blue eye gene, then the child stands a good chance of having blue eyes as well. Additionally, recessive genes can be passed down and even skipped a generation or two, this could mean that blue eyes that have been passed down from the grandparents could suddenly show up in the next generation, if both parents also have a recessive gene for blue eyes.
Which parent determines eye color?
The Simple Answer:
Both parents determine the eye color of their child. Although the color of a child’s eyes will usually be a combination of both the mother and father’s eye colors, it is the father’s genes that are the more influential.
While a mother’s genes only influence the possibilities of the eye colors a child can have, based on the pigment she carries, it is the father’s genes that ultimately determine the shade of the eye color.
This means that a child can have two different eye colors, depending on which combination of genes they inherit from each parent.
What is the rarest eye color?
The rarest eye color is amber. It is estimated that only 5% of people worldwide have amber eyes. Amber eyes appear golden, yellow or honey in color and occur due to the abundance of a pigment called lipochrome.
Amber eyes are primarily seen in people of the Middle East and parts of South Asia, but have been known to appear in other parts of the world too. Amber eyes may also be the result of a combination of two different colors of eyes, typically grey and green.
In some cases, amber eyes may even be described as hazel due to their tendency to vary in shade.
Can baby have blue eyes if parents don t?
Yes, it is possible for a baby to have blue eyes even if their parents do not. This is because eye color is determined by a person’s genetic makeup. Both parents contribute genes that make up the child’s eye color, however, having no genes for blue eyes does not mean the child cannot have blue eyes.
Some individuals have inherited a gene from a grandparent or even further back in the family tree that can give them blue eyes. Additionally, babies can be born with heterochromia, a rare genetic condition which gives them eyes of two different colors.
In this case, one eye could be blue and the other brown, even if neither parent have blue eyes.
How do kids get blue eyes?
Having blue eyes as a child is a unique trait, and it depends on the baby’s genetic makeup. Blue eyes are the result of an allelic pair, with both parents having at least one blue-eyed gene. To determine eye color in children, the two “dominant” alleles in the gene pair interact, with one being more powerful than the other.
Since these alleles can be blue, green, brown, gray, hazel, etc. , combinations of different alleles will lead to different eye colors.
If both parents carry a blue-eyed gene, the baby will likely have blue eyes. It is also possible for a baby to inherit different versions of the gene from each parent, leading to a blue/green eye color, blue/brown eye color, or a completely different color depending on the gene combination from the parents.
Although it is possible for the baby to have different colored eyes than the parents, blue eyes are often a common trait in families and can be passed on from generation to generation.
Does one parent have to have blue eyes for a child to have blue eyes?
No, one parent does not necessarily have to have blue eyes for a child to have blue eyes. Eye color is determined by a combination of genetic factors, not simply the genes from a single parent. Eye color is primarily determined by genetic inheritance, but it is also affected by environmental and hormonal factors.
Most babies are born with either blue or dark brown eyes, but eye color can change over time. For any given person, eye color is determined by a complex mix of genetic variation that is inherited from both parents.
Each parent contributes different versions of several genes that the child inherits. The particular versions of these genes determine the amount of melanin in the front of the eye, which determines a person’s eye color.
Therefore, in order for a child to have blue eyes, one or both parents would need to carry the gene variant that codes for blue eyes.
What is special about blue eyes?
Blue eyes are beautiful and unique in their own special way. They are considered to be a rare color, although it is a combination of two common eye colors: brown and gray. Blue eyes can range in shade from bright, sky blue to deep, navy blue, and the flecks of color found in blue eyes can vary from person to person.
This variation makes them even more special and eye-catching.
The rarity of blue eyes often gives the impression of exclusivity and mystery. It’s thought that most people with blue eyes originated in Northern Europe, although the majority of individuals worldwide do not have blue eyes.
This makes blue eyes even more special because they stand out in comparison to other eye colors.
The way light reflects off of blue eyes is striking and beautiful. Light has the ability to be absorbed and reflected differently in each eye color, and blue eyes tend to reflect light in a unique way.
Blue eyes can seem to change color in different lighting, sometimes appearing greener or hazel.
Overall, blue eyes are a unique eye color that adds beauty and intrigue to anyone who has them. They stand out among the crowd, and their rarity makes them all the more special.
