Yes, blue eyes are recessive. This means that it is likely that both parents must have the gene for blue eyes in order for their children to have blue eyes. A person with one blue eye and one non-blue eye is likely to be a carrier of the blue-eyed gene, meaning they can pass it on to their children, even if they do not have blue eyes themselves.
When it comes to eye color, the genetic diversity is not very wide. Blue, brown, and green are the most common colors, and all of them are considered to be dominant genes—meaning that if one gene is present, it is likely to be seen in the resulting eye color.
However, blue eyes are the only eye color that is considered to be a recessive trait, which means that both parents must have the gene for blue eyes in order for their children to have blue eyes.

What is the most recessive eye color?
The most recessive eye color is generally considered to be blue. This is because the brown and green pigmentation genes (E/e, known as the ‘B allele’) are dominant, while the blue eye color gene (known as the ‘b allele’) is recessive.
If two copies of the ‘b allele’ are inherited from both parents (Bb or bb), the result is blue eyes. The eye color of an individual is determined by the pigment cells in the iris, which can range from shades of blue, green or brown, depending on the genetic makeup.
Some people may have a mixture of both blue and brown pigment in their eyes, resulting in a hazel or gray color. Blue eyes are also somewhat linked to the European populations, however, they have been found to exist in all other parts of the world.
What eye colors are recessive?
The color of a person’s eyes is determined by the alleles that they inherit from their parents. Eye color is a polygenic trait, which means it is determined by more than one gene. Some of which are dominant and some of which are recessive.
The most common eye colors, brown and blue, are both technically dominant traits. That said, there are certain combinations of genes that can produce recessive eye colors, such as green, hazel, and gray.
Green eyes are sometimes referred to as “honeybee eyes” due to their rarity and lovely hue. They occur when a person inherits two copies of the gene for green eyes from their parents. Hazel eyes are a mix of brown and green and are typically created when a person inherits one gene for green eyes and one for brown eyes.
Gray eyes occur when a person inherits two copies of the gene for gray eyes.
What is the rarest eye color in the world?
The rarest eye color in the world is thought to be green. Although green eyes are found in many parts of the world, they are the rarest eye color among humans. Green eyes are the result of low levels of melanin in the iris, which makes them appear to be green in color.
While the estimated percentage of people with green eyes is only 2–17%, the condition is becoming more common in recent years, particularly among those of European ancestry. Furthermore, green eyes tend to become lighter and more yellow in hue as we age.
Is Grey eyes dominant or recessive?
The answer to this question depends on the genetics of your particular situation. Generally speaking, gray eyes are considered to be a recessive trait. This means that to have gray eyes, both of your parents must have gray eyes or another eye color plus a gene associated with gray eyes.
For instance, if one parent has blue eyes and the other has gray eyes, the child may have either blue eyes or gray eyes depending on whether the gene for blue eyes or the gene for gray eyes is dominant.
Additionally, even if both parents have gray eyes, the possibility still exists that a child may have a different colored eye. The eye color of the child would then depend on dominant and recessive genetic traits within the parents.
Can 2 brown-eyed people have a blue eyed baby?
Yes, it is possible for two brown-eyed people to have a blue-eyed baby. This phenomenon is called genetic recombination and is a result of the combination of genetic information from both parents. It is caused by a specific combination of genetic information that allows a recessive gene for blue eyes to show up in the child, even when both parents have brown eyes.
To have a blue-eyed baby, both parents need to carry the recessive gene for blue eyes. If one of the parents carries the gene, but the other doesn’t, the baby will still have brown eyes even if the other parent has blue eyes.
Therefore, it is possible for two brown-eyed parents to have a blue-eyed baby by chance. However, the odds of having a blue-eyed baby decrease if two brown-eyed parents who both lack the gene are the parents.
Do purple eyes exist?
No, unfortunately purple eyes do not exist. Eye color is determined by the amount of melanin (a pigment) in the iris of the eye. The range of eye colors that can occur naturally can include shades of brown, green, blue, gray and even shades of amber or hazel.
Although it may appear that some eyes are purple or violet in tone, this is usually an effect of light reflecting off the iris. The eyes might appear to be purple from certain angles or under particular lighting conditions, but in reality, their color is likely to be a shade of blue or green.
How rare is grey eyes?
Grey eyes are considered a very rare eye color and can be found in only 1-2% of the world’s population. Grey eyes are a lighter form of hazel eyes — hazel eyes often contain grey flecks, as well as shades of brown, green and amber.
In general, the rarer the combination of colors in your eyes, the rarer your eye color is considered. For example, someone with predominantly grey eyes and only a hint of one of the other colors would be considered very rare.
People with grey eyes are often mistaken for having blue eyes, but can be distinguished by their lighter and more muted tone. Grey eyes have been popularized in fiction and media, with famous people such as Kate Hudson, Zac Efron, Cardi B and Chris Hemsworth all having this eye color.
Are GREY eyes blue or green?
Grey eyes are not typically considered blue or green, but rather a mix of both. Grey eyes contain the same amount of melanin as blue eyes, but their lower concentrations create the grey color. Grey eyes contain a mixture of blue, green, and minute amounts of other colors, resulting in a beautiful, pale-grey or steel-grey color that is unique to that individual.
It is not uncommon to have eyes of various shades between blue, green and grey. There is even a unique variant of grey eyes called “spangled grey” which includes distinct flecks of green, blue and gold, creating an entirely unique eye coloration!.
Which parent determines eye color?
Eye color is determined by a combination of genetic factors passed down from both parents. Kid’s eye color is dependent upon the combination of two eye colors from both parents, which is influenced by the amount and type of pigment in the iris.
Brown is the most common eye color, which is usually inherited from both parents. Blue eyes are a recessive trait and usually occur in combination with another lighter color. If both parents carry this recessive trait, then the child will most likely have blue eyes.
However, if one parent has blue eyes and the other has brown eyes, the child will most likely have hazel eyes. Green eyes are a combination of the amount and type of pigment that is present in both the brown and blue color spectrum, and may be influenced by factors such as geography and ethnicity.
Ultimately, it is up to several genetic factors to determine the eye color of a child.
Is eye color inherited from the mother or father?
The genetic code for eye color is found on the chromosome which is passed from both parents, the mother and father. Each parent contributes one chromosome to a pair, giving the child two copies of the eye color gene.
Thus, it is likely for a child to take traits from both parents and mix the eye color genes together, giving the child a combination of eye colors from both parents. For example, a child could have hazel eyes if the father has a pair of blue eyes and the mother has a pair of brown eyes.
However, it is possible for a child to inherit one eye color from either the father or the mother, or even the same eye color as both parents, depending on the inherited gene pair.
Can a brown-eyed parent and blue-eyed parent have a blue-eyed child?
Yes, it is possible for a brown-eyed parent and a blue-eyed parent to have a blue-eyed child. This is because eye colour is a genetically inherited trait which is determined by the genetic code passed from parents to their children.
The code for eye colour is passed down in the form of alleles, in a Dominant/Recessive genetic pattern.
Blue eyes occur because of a recessive gene called the ‘Blue eye’ allele. For a child to have blue eyes, they will need to have inherited two recessive genes, one from each parent. If one of the parents has brown eyes and is carrying a recessive blue eye gene (often referred to as a Brown Eye Carrier), and the other parent has blue eyes, then it is possible for their child to have blue eyes.
In this way, a brown-eyed parent and blue-eyed parent can have a blue-eyed child, as both parents are carrying the recessive blue eye gene.
What genes are inherited from father only?
Certain genes are inherited from the father only, and are known as “Y-linked” or “Y-linked genes”. These genes are located on the Y chromosome, which is one of two sex chromosomes present in each cell of a father’s body.
Genes located on the Y chromosome are mainly responsible for male-specific traits and are only passed from the father to his sons. Examples of traits determined by Y-linked genes include male pattern baldness, shape and color of the eyes, the taste of a certain type of food and more.
Some diseases like hemophilia, Duchenne Muscular Dystrophy and Klinefelter Syndrome are also determined by Y-linked genes. Because females lack the Y chromosome, they cannot inherit any traits determined by Y-linked genes and can therefore only be inherited from the father.
Is eye Colour determined by grandparents?
No, eye colour is not determined by one’s grandparents. Eye colour is determined by the genetic inheritance of a person’s parents. When the egg and sperm join together during conception, they carry with them genetic information from both parents that combines to make up the full genetic makeup of an individual.
The colour of a person’s eyes is determined by the genetic combination of their parents. Therefore, while grandparents may influence someone’s eye colour indirectly, they are not the direct source of eye colour.
Where do hazel eyes come from?
Hazel eyes are a result of various combinations of genetic traits, as well as environmental factors. They are typically a mix of multiple colors including greens, yellow, hazel, brown, and amber. It is believed that the combination is caused by a variation of melanin production, the pigment responsible for eye color, in the iris.
In addition, some research has suggested that eye color may also be influenced by neighboring genes, referred to as statistical genetic interactions.
Generally, hazel eyes are most commonly seen in people of European or North African descent, although they can occur in people of any ethnicity. In certain areas, they are found more frequently than others; for example, hazel eyes may be more common in Scotland and Ireland than in other parts of the world.
The tendency to express hazel eyes may also be influenced by environmental factors, such as diet and lifestyle habits. In addition, certain gene mutations- and recessive genes- can cause the expression of hazel eyes in individuals who would not otherwise have that eye color.
In conclusion, hazel eyes come from a combination of genetic and environmental influences. While there is no one specific cause for hazel eyes, these eyes are more commonly seen in individuals of European or North African descent.
