What Do Brown And Hazel Eyes Make?

What Do Brown And Hazel Eyes Make
How Are They Similar and Different? – Brown and hazel eyes are often put into the same category. In certain types of light, especially low light, hazel eyes can appear to be light brown. However, hazel eyes are far more diverse compared to brown eyes. When eyes are hazel, they are brown mixed with amber and green.

In some cases, there are shades of gray, blue, and gold within the iris too.
Brown eyes may also have some green in them.
However, it is not nearly as noticeable as it is when someone has hazel eyes.
With brown and hazel eyes, the other colors may appear as rings or flecks of color.
This is part of what makes these eyes so distinctive.

Due to the differences, no set of brown or hazel eyes is like those of another person.

Can brown and hazel eyes make blue?

Is it possible for two brown eyed people to have a child with blue eyes? Editor’s Note (4/14/2021): The following article and diagrams present an over-simplified, outdated version of eye color genetics. Eye color is influenced by at least 50 genes, not all of which are well understood.

Yes. The short answer is that brown-eyed parents can have kids with brown, blue or virtually any other color eyes.
Eye color is very complicated and involves many genes.
To begin to understand how parents with brown eyes could have blue-eyed children, let’s imagine that eye color is due to a single gene, EYCL3, which comes in two versions or alleles, brown ( B ) and blue ( b ).

Remember that for most genes (including eye color), you have two copies of each gene, and that you inherited one from your mother and one from your father. The brown version of the eye color gene ( B ) is dominant over the blue version ( b ). Dominant means that if either of your genes is the B version, then you will have brown eyes.

Genetically speaking, then, people with brown eyes could be either BB or Bb while people with blue eyes could only be bb,
Example of a one-gene model for eye color.
For two parents with brown eyes to have a blue-eyed child, both parents must genetically be Bb,
When this happens, there is a 1 in 4 chance that these parents will have a bb child with blue eyes.

Unfortunately, eye color is not as simple as this. Besides the EYCL3 gene described above, at least two other genes, EYCL1 and EYCL2, are also involved. Although this set of genes explains how people can have green eyes, it does a poor job of explaining how blue-eyed parents could have brown-eyed children or how anyone can have hazel or gray eyes at all.

To understand green eyes in all of this, we only need to review EYCL1 and EYCL3 (EYCL2 is a poorly understood brown eye color gene).
Remember, EYCL3 has two versions, brown ( B ) and blue ( b ).
EYCL1 also comes in two versions, green ( G ) and blue ( b ).
The way these genes work is that if you have a B allele, you will have brown eyes ( B is dominant over b and G ), if you have a G allele and no B allele, you will have green eyes ( G is dominant over b ) and if you have all b genes, then you will have blue eyes.

Example of a two-gene model for eye color. I hope this helps to answer your question. As you can tell, while some progress has been made, eye color is a very complex, polygenic trait that is not yet fully understood. : Is it possible for two brown eyed people to have a child with blue eyes?

Can two brown eyed parents have a child with hazel eyes?

Is there a way to predict my baby’s eye colour? – Not really. Two brown-eyed parents are likely to have a brown-eyed child, but could potentially have a child with blue, green or hazel eyes, depending on the combination of genes from each parent. Two blue- or green-eyed parents are likely to have a child with blue or green eyes (or a blueish-greenish combo), but it’s possible they will have a brown- or hazel-eyed child.

What do two parents with hazel eyes make?

What color eyes will my child have? – There’s no guarantee when it comes to your offspring’s eye color. While a baby inherits half of their eye color genetics from one parent and half from the other parent, the way that the genes interact also plays a role in determining eye color.

Differences in eye color are also influenced by differing amounts of melanin, the pigment responsible for eye color (plus hair color and skin tone). For instance, many white non-Hispanic babies are born with blue eyes because they don’t have the full amount of melanin present in their irises at birth.

As the child grows older, if they’ve developed slightly more melanin in their irises, the eyes will be green or hazel, When the iris stores a lot of melanin, the eyes will be amber (a golden brown), light brown or dark brown. Even though you don’t know the amount of melanin your baby will have, you can still get a pretty good sense of eye color from the parents’ eye colors.

Two blue-eyed parents are likely to have a blue-eyed child, but it’s not guaranteed. Two brown-eyed parents are likely to have a brown-eyed child. Again, it’s not guaranteed. Two green-eyed parents are likely to have a green-eyed child, although there are exceptions. Two hazel-eyed parents are likely to have a hazel-eyed child, although a different eye color could emerge. If one of the grandparents has blue eyes, the odds of having a baby with blue eyes increases slightly. If one parent has brown eyes and the other has blue eyes, the chances of having a brown-eyed or blue-eyed baby are roughly even.

The Fertility Institutes, which offers fertility services in California, New York, Utah and Mexico, offers the following odds of a baby’s eye color based on the parents’ eye colors. (Due to rounding, percentages don’t always add up to 100%.)

Both parents with brown eyes: 75% chance of baby with brown eyes, 18.8% chance of baby with green eyes, 6.3% chance of baby with blue eyes. Both parents with blue eyes: 99% chance of baby with blue eyes, 1% chance of baby with green eyes, 0% chance of baby with brown eyes. Both parents with green eyes: 75% chance of baby with green eyes, 25% of baby with blue eyes, 0% chance of baby with brown eyes. One parent with brown eyes and one parent with blue eyes: 50% chance of baby with brown eyes, 50% chance of baby with blue eyes, 0% chance of baby with green eyes. One parent with brown eyes and one parent with green eyes: 50% chance of baby with brown eyes, 37.5% chance of baby with green eyes, 12.5% chance of baby with blue eyes. One parent with blue eyes and one parent with green eyes: 50% of chance of baby with blue eyes, 50% chance of baby with green eyes, 0% chance of baby with brown eyes.

Keep in mind that it may take six to 12 months for a baby’s true eye color to emerge, so the color you see at birth can certainly change. SEE RELATED: Is it true all babies are born with blue eyes?

How do kids get hazel eyes?

Inheritance of eye colors – Now we’re finally ready to look at some examples of how hazel eyes might be inherited. First, let’s imagine a blue-eyed parent with bbmm and a hazel-eyed parent with GGMM, The blue-eyed parent can only give bm to his children and the hazel-eyed parent can only give GM,

So, all of their children will be GbMm or hazel-eyed carriers for green and blue eyes.
Let’s look at a more interesting example: a blue-eyed parent, bbMM, and a green-eyed parent, GGmm,
This time, the blue-eyed parent can only give bM,
The hazel-eyed parent can only give Gm,
The end result is all GbMm or hazel eyes! A blue and a green-eyed parent will have all hazel-eyed kids.

This is one of the reasons I like the modifier gene explanation so much. It can help explain how green and blue-eyed parents might have hazel-eyed kids. Finally, let’s tackle a tough one. Imagine two hazel-eyed parents GbMm, What would their kids look like? For this, we need to bring out the old Punnett square.

	G M	G m	b M	b m
G M	GG MM	GG M m	G b MM	G b M m
G m	GG M m	GG mm	G b M m	G b mm
b M	G b MM	G b M m	bb MM	bb M m
b m	G b M m	G b mm	bb MM	bb mm

From this the results are that there is a 4 in 16 chance for blue eyes, a 3 in 16 chance for green and a 9 in 16 chance for hazel. Even though this looks awful, it might be possible to figure things out if this were all that was involved. Now imagine adding the brown gene to the mix.

And another modifier that decreases melanin from BEY2 instead of increasing melanin from GEY,
And now sprinkle in different modifier genes that increase or decrease melanin made by different amounts.
And modifier genes that affect the modifier genes.
In reality, eye color may be a result of all of these ideas – hazel eye color genes, modifier genes, and different versions of BEY2 and GEY ! As you can see, it all gets complicated pretty quickly.

We should be thankful that green, blue, and brown are as simple as they are. : How do the genes for uncommon eye colors work?

What color eyes will a baby have if parents have brown and hazel eyes?

What about hazel eyes? – Hazel eyes are hard to predict because it’s typically a mixture of brown, green and amber shades. If both the parents have hazel eyes, there are 99% chances that the baby will also have hazel eyes. If both the parents have brown eyes, there is a 75% chance that their child will have brown eyes.
