This has to do with the fact that blue eyes are supposed to be recessive to brown eyes. This means that if a parent has a brown eye gene, then that parent will have brown eyes. Which makes it impossible for two blue-eyed parents to have a brown-eyed child -- they don't have a brown eye gene to pass on!
What color eyes can two blue eyed parents have?
First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. Eye color is not the simple decision between the brown (or green) and blue versions of a single gene. There are many genes involved and eye color ranges from brown to hazel to green to blue to…
Will two blue eyed parents always have a blue eyed child?
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
What is the rarest eye color?
Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world's population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
Can 2 brown eyes make hazel eyed baby?
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.

Can a brown eyed and blue eyed parent have a green eyed child?
Taking a Deeper Look at Eye Color Possibilities
Eyes come in different colors other than just brown and blue, because eye color is controlled by how much melanin we produce. Parents with brown eyes may give birth to children with dark brown eyes, light brown eyes, hazel eyes, green eyes, or blue eyes.
Can 2 green eyes make a brown?
Back to the Simple Model. In the simple model, two green-eyed parents could not have a brown-eyed child. It turns out that this is because in this model, everyone with one or two T's for the HERC2 gene is predicted to have brown eyes. Scientists would say that the T version is dominant over the C version.
Do people have GREY eyes?
Less than 1 percent of people have gray eyes. Gray eyes are very rare. Gray eyes are most common in Northern and Eastern Europe. Scientists think gray eyes have even less melanin than blue eyes.
What are the chances of a mixed baby having blue eyes?
Recessive and Mixed Genes
Depending on whether the other gene is dominant or recessive, the couple's offspring have a 1 in 2 chance of inheriting blue eyes, and a 1 in 2 chance of inheriting brown eyes.
Which parent determines eye color?
What determines a baby's eye color? In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby's eye color is determined by the parents' eye color and whether the parents' genes are dominant genes or recessive genes.
What is most attractive eye color?
While hazel was found to be the most attractive eye color in females. When it came to the most attractive eye color in females, the results were very different. Hazel eyes topped the list as the most popular, with 65 out of 322 total matches—or 20.19 percent.
What causes hazel eyes?
The combination of having less melanin (as with green eyes) and a lot of melanin (like brown eyes) make this eye color unique. The color combinations in shades of green, brown, and gold are endless with hazel eyes, depending on the concentration of melanin. The light scatters as it does with blue and green eyes.
Are GREY eyes dominant or recessive?
Are gray eyes recessive or dominant? Gray eyes are neither recessive nor dominant. Scientists used to think that a person's eye color was caused by one dominant gene, and that brown eyes were dominant while lighter eyes (blue, green, hazel and gray) were recessive.
Are blue eyes green recessive?
Blue will always be recessive. If both parents have a blue allele, it is likely that the child will have blue eyes. However, if one parent has green eyes and the other blue, your child will most likely have green eyes, as green is dominant over blue.
What are gray eyes?
Gray eyes may be called “blue” at first glance, but they tend to have flecks of gold and brown. And they may appear to “change color” from gray to blue to green depending on clothing, lighting, and mood (which may change the size of the pupil, compressing the colors of the iris).
Is GREY the rarest eye color?
Unusual eye colours
Grey eyes are amongst the rarest eye colours and while many associate grey eyes with being blue, they are not quite the same despite them both having low levels of melanin. Pink and pale red eyes are also incredibly unusual eye colours and occur in people who have albinism.
How rare are blue and green eyes?
Part of the reason they hold our attention is because they are extremely rare. While the science is somewhat scattered, the current research suggests that only around 3-5% of the human population has true blue green eyes. That's pretty amazing when you consider there's over 7 billion people on the planet.

Can a brown eyed mother and blue eyed father?
She can pass either of these alleles on to her offspring, so in theory, even though brown is dominant, a brown eyed mom and a blue eyed dad could give birth to a blue eyed child.
Does blue eyes skip a generation?
This is because you each only have blue versions to pass on to your children. That means that your kids will most likely all have blue eyes. So once dominant traits like dark eyes aren't passed on to the next generation, they can be “lost.” Genes can be passed on from generation to generation.
Do blue eyes have blue pigment?
There is No Blue Pigment in Blue Irises
For almost everyone — even people with blue eyes — the back layer (called the pigment epithelium) has brown pigment in it. The front layer of the iris (called the stroma) is made up of overlapping fibers and cells.
