The color of a baby’s eyes is determined by their genetic makeup. Typically, all babies are born with blue eyes and their eye color won’t begin to change until around 3-6 months of age. As they get older, their eye color will become more developed and will darken to its true color.
Eye color is determined by the amount of Melanin (the pigment that gives color) in the iris, and is influenced by genetics. The iris of the eye, the colored part, contains two types of melanin – eumelanin and pheomelanin – which work together to determine the eye’s color.
The amount and ratio of these pigments vary from person to person, which is why no two people have the same eye color. The ratio of melanin in each person’s eyes is determined by their genetic heritage and this determines their eventual eye color.
Eye color is mostly determined by genetics and some people’s eyes may range from black to blue, brown, or even yellow. People with brown eyes generally have more melanin in their irises than those with blue eyes, and people with black eyes usually have even more melanin.
Some babies may even have two different colored eyes if they inherit two different sets of genes.
In the end, a baby’s eye color is determined by the combination of genetics they inherit from the parents.

Which parent determines eye color?
Eye color is determined by both parents, but not necessarily in equal measure. Eye color is determined by a combination of genetic traits passed down from both parents. For example, if one parent passes down a gene for brown eyes and the other for blue eyes, then the child will likely have a combination of both.
The same is true for any combination of eye colors, including green, hazel, gray, and variations of those colors. Each parent will pass down different genes for eye color, so even if both parents have the same eye color, the child may end up with a different eye color.
In some cases, a parent may not pass down a gene for the same eye color, so the child’s eye color could be completely different from both parents. Ultimately, the combination of genes that the parents pass down will determine the child’s eye color, so both parents play a role in determining the eye color of their child.
Is eye color inherited from the mother or father?
Eye color is a polygenic trait and is determined by genetic variants that are inherited from both the mother and father. To most of us, our eye color appears to be one solid color, but if you look at an eye up close you can actually see a blending of different colors.
This is because everyone’s eyes contain a mix of genetic variants from the mother and father. Additionally, eye color can change in some people as they get older, as the amount of melanin in the iris can decrease with age.
Because eye color is a complex trait determined by multiple genes, it is impossible to easily predict what color eyes a baby will have by looking at the eye color of their parents.
Can a brown-eyed parent and blue eyed parent have a blue eyed child?
Yes, a brown-eyed parent and a blue-eyed parent can have a blue-eyed child. This is because eye color is determined by genes and everyone has two copies of each gene. Each parent will pass on one version of a gene to their child, and the combination of genes can result in the child having a different eye color than either parent.
In the case of brown and blue eye color, each parent will pass on a version of the gene responsible for brown eyes (known as the B allele) and one of the versions responsible for blue eyes (known as the b allele).
Depending on which version of the gene a child receives from each parent, their eye color can be brown, blue, or somewhere in-between. If a child receives a b allele from both parents, then they will have blue eyes.
In summary, a brown-eyed parent and blue-eyed parent can have a blue-eyed child if both parents pass on the b allele version of the gene, resulting in the child having blue eyes.
What’s the rarest eye color?
The rarest eye color is amber. Estimates vary, but according to World Atlas, just 5 percent of the world’s population has green eyes, with amber eyes being even rarer. Amber eyes range from light honey to a more golden yellow hue.
While rare, amber eyes can be found in many countries, including the United States, Finland, Japan, and Saudi Arabia. The mutation occurs most frequently in Asian countries, and some believe it may offer a benefit in poor light conditions and for people who enjoy being near the sea.
What genes are inherited from father only?
The answer to this question depends on whether you are talking about humans or another species. In humans, the father only provides genetic information to his offspring in his Y-chromosome, which contains the genetic material that determines male characteristics.
Other specific traits may be determined by genes on the Y-chromosome, but these can be highly variable. Generally, the traits that are passed along solely from the father to his offspring are those related to sex determination and some other specific characteristics such as eye color.
In some cases, the father may also pass down some genetic mutations, but these are quite rare.
In other species, the father may pass along certain specific genes to his offspring that are not found in the mother’s genetic material. For example, chickens can have a Dominant White gene that is only passed from a father to his offspring.
This gene produces a white plumage in chicks, so it can be used to selectively breed chickens for a specific color. Other species may have similar traits that are determined solely by the father.
Overall, the answer to this question depends largely on the species in question. In humans, the father’s genetic contributions are limited mostly to those related to sex determination and a few other specific traits.
In other animals, it may be possible for the father to pass down genetic traits that are not found in the mother.
Can a brown eyed mom have a blue eyed dad?
Yes, a brown eyed mom can have a blue eyed dad. This is because of genetics. Every person has two sets of genes for eye color; one from each parent. When those sets of genes are combined, the result is the eye color of the child.
If a brown eyed mom and a blue eyed dad have a child, the child could have either eye color or a combination of both. Genetics is complex and it is not possible to predict with certainty what color a child’s eyes will be, but it is certainly possible for a brown eyed mom to have a blue eyed dad.
Can a baby have green eyes if the parents don t?
Yes, it is possible for a baby to have green eyes even if the parents don’t. Due to the variation in eye colors, two people with different colored eyes could produce a baby with green eyes. These variations are due to genetics.
Genes from both the parents determine the eye color of their baby, which can be one of the parents’ colors or sometimes a different color. For example, if a parent has blue eyes and the other has brown eyes, their baby could have either blue or brown eyes, or even green.
It is not uncommon for babies to have green eyes, especially if one parent has brown eyes and the other has blue eyes. Green eyes are considered to be a unique eye color that is produced due to a combination of the various shades of blue and brown pigments.
What color eyes will a child have if both parents have blue eyes?
The color of eyes that a child will have if both parents have blue eyes is not certain – it is determined by genetics and dependent on the other genes present in both the mother and the father. Generally speaking, the dominant eye color gene (brown eye color) will override the recessive gene for blue eyes, although both genes can be passed onto the child and may express themselves differently depending on the combination of genes inherited from both parents.
Generally, the odds of the child having blue eyes is about 75%. However, if both parents are carriers of recessive alleles for both blue and brown eyes, the chances for the child to have blue eyes increases to about 90%.
What are the chances of a blue eyed baby with brown eyed parents?
The chances of a blue eyed baby with brown eyed parents is technically not possible, as brown eyes are the most dominant trait among humans. To produce a blue eyed baby, both parents must carry the recessive gene for blue eyes.
Brown eyed parents are not likely to both have the recessive gene, although it is technically possible. The odds of a brown eyed couple having a blue eyed baby is somewhere between 0-2%. The odds increase if either parent, or a relative of either parent, has blue eyes.
In these cases, the odds are closer to 25%. It is also possible for a parent to carry the recessive gene and be completely unaware. To know for sure, genetic testing can be conducted.
Can blue eyes be dominant over brown?
Yes, blue eyes can be dominant over brown. This means that if both parents have a different eye color, a child may display the dominant eye color. Brown eye color is a dominant trait, meaning that if both parents have a different eye color, a child is more likely to have brown eyes, even if one parent has blue eyes.
However, blue eye color is considered to be a recessive trait, so in order for a child to have blue eyes, both parents must have the gene that codes for blue eyes. If only one parent has the recessive gene, the child will likely have brown eyes, which is the most common eye color.
Additionally, if both parents have blue eyes, the child is more likely to have blue eyes than brown.
It is important to know that eye color is not solely determined by genetics. In some cases, environmental factors can also influence a person’s eye color and can cause the colors to change over time.
For example, a person’s eye color may become lighter or darker due to factors that are outside of their control.
In conclusion, blue eyes can be dominant over brown, but it depends largely on the genetics of each individual’s parents. Both parents must possess the recessive gene that codes for blue eyes in order for a child to have blue eyes.
However, environmental factors can also affect the color of a person’s eyes, which is why some people’s eye colors may change over time.
Do babies get eye color from mom or dad?
The short answer is that babies can get their eye color from either their mom or dad, or a combination of both. However, there is a bit more complexity to the answer.
Eye color is determined by the amount and type of pigment (melanin) in the iris of the eye. Different amounts and densities of melanin give each eye color its unique hue. Females have two X chromosomes, and males have one X chromosome and one Y chromosome.
The portion of the X chromosome responsible for eye color can be either the same or different on each chromosome, but the X chromosome from the father will always appear alongside a Y chromosome from the father.
Eye color is inherited from both parents. However, the amount of effect that the mother or father has on the eye color a baby will have is not determined by which parent the baby looks like or by what the baby’s gender is.
Instead, eye color is determined by the specific combination of genes each parent gives to their child. If both parents have blue eyes, the chances of the baby having blue eyes are much higher than if one parent has blue eyes and the other has brown.
It is also possible for a baby to have different colors in each eye, depending on the combination of alleles the baby receives from their parents. In some cases, the eye color may not even appear until a few months after birth.
How can 2 brown eyed parents give birth to a baby with blue eyes?
It is possible for two brown-eyed parents to have a baby with blue eyes. This is due to a phenomenon known as genetic blending, or allele crossing over, which occurs when some of the genetic material (alleles) in reproductive cells (gametes) changes before they combine.
When the parents’ gametes combine, they create a unique genetic makeup for the baby that can include traits different from either parent. Brown eye color is a dominant trait, meaning that in order for a baby to have blue eyes, both parents must carry a recessive gene for blue eyes.
It is possible for two brown-eyed parents to each carry a recessive gene for blue eyes without either of them exhibiting the blue-eyed trait. When the genes for both parents combine, the baby has a 25% chance of having blue eyes.
It is also possible for two blue-eyed parents to have a baby with brown eyes, providing each parent carries a recessive brown-eyed gene.
Who has stronger genes mother or father?
This is a difficult question to answer definitively because there are both genetic and environmental factors that have an influence on the traits passed on from parents to their children. Generally speaking, it is thought that a child is likely to inherit equal amounts of genetic information from the mother and the father.
However, certain genetic diseases and certain traits may be inherited more strongly from either the mother or the father. For example, a mother can pass on a trait related to skin or eye color more strongly than a father because these traits are linked to components of mitochondrial DNA, which always comes from the mother.
Similarly, a father can pass on certain Y-chromosome linked genetic traits more strongly than a mother. Ultimately, the answer to this question is variable and dependent on many factors.
What eye color is dominant?
The term “dominant” when referring to eye color is used to describe the eye color is most common or most often seen in a given population. The most dominant eye color depends on the population being discussed.
For example, in the United States and Europe, the most dominant eye color is usually shades of brown. In the African population, dark brown eyes are the dominant eye color with blue eyes being very rare.
In Asia, the most dominant eye color is usually shades of black. In Japan, eye color is very diverse but tends to range from dark brown to lighter shades of brown to black. In other regions around the world, eye color can vary significantly depending on population.
