Top 30 Doctor insights on: How Can A Dad With Brown Eyes And A Mom With Hazel Eyes Have A Baby With Blue Eyes In brief: Brown dominant. Two brown eyed parents that produce a blue eyed child are both carriers of the blue eye recessive gene. Brown dominates. They both have bb for eye color. This means a 1/4 chance for blue, a 50% chance for bb carrier brown, a 25% chance for full bb brown. Two brown eyed parents that produce a blue eyed child are both carriers of the blue eye recessive gene.

Katla 1 Katla produces basaltic magmas that typically do not cause explosive eruptions. 2  Many scientists attribute a layer of ash deposited in the North Atlantic and across Europe some 12,000 years ago to a massive eruption of Katla.

What Color Will My Baby's Eyes Be? If you have blues and your partner has brown, then your baby’s eyes have a 50% chance of either one. If both you and your partner have blue eyes, then your baby’s eyes will most likely not change and remain that sparkling baby blue! Mats, Richard A and Larsson Sturm.

- My baby was born with very blue eyes and long, dark brown hair. Majority of the long, dark hair fell out between 2-4 months of age. The hair that grew in is a lighter brown. His eyes are still almost the same at 10 months. We are fairly certain they will stay blue, because they have changed just a tiny bit towards blue/grey.

Eye Color Her eyes may be blue only temporarily; babies' eyes can change color if the brown pigment melanin develops as they grow. We used to think of brown being dominant and blue being recessive.. But modern science has shown that eye color is not at all that simple.

10 Unbelievable Facts You Didn't Know About Redheads 4. Red hair and blue eyes is the rarest combination in the world. The majority of natural redheads have brown eyes, with others likely to have hazel or green shades. But like red hair, blue eye colour is a recessive trait, meaning that both parents must carry the gene for a child to be blessed with it. This makes those with red hair and blue eyes the rarest minority in the world, with only 1% having both. So, each one is about as rare as a four-leaf clover.

Are blue eyes more predominant in some races than others? Mutation in certain genes can lead to dysfunction in melanin production which results in white skin, white hair and red eyes. This phenomenon is known as albinism and it has been frequently recorded in certain animals too. Eiberg claims that all human race originally had brown eyes and that blue eyes appeared only 10000 years ago. Moreover he assumes that one single man was responsible for this, when mutation occurred in his genes precipitating changes in his irises he was born with blue eyes, approximately 6000 - 10000 years ago.

Can two blue eyed parents have a brown eyed child? Two brown eyed parents can have a blue eyed child because they can carry a dominant brown gene and a recessive blue. They could both pass on a recessive blue gene giving the child blue eyes. The only way i can see blue eyed parents having a brown eyed child is if one of them has the same problem that i do.My eyes are different colours, both have blue, green and brown in them. Its caused through damage to the gene which passes on colour causing the eyes not to get enough brown pigment.f you have a gene for both, you will have borwn eyes. 2 blue eyed parents will have a blue eyed child. Once in a blue moon, genetics takes a break (see below...but the chances are so slim, a paternity test is in order). HOWEVER 2 brown eyed parents can have a blue eyed child.

How Blue Eyed Parents Can Have Brown Eyed Children Normally this wouldn’t be enough to explain how blue eyed parents can have a brown eyed child. Because of how eye color works (see below), if one gene can cause brown eyes, it would dominate over another that causes blue. In fact, that is what happens with green eyes in the older model.he reason these two genes can explain darker eyed kids with lighter eyed parents is that the two genes need each other to work. And that the blue versions are broken genes. Here is what things look like: The key is that if someone makes a lot of pigment in the front part of their eye, they have brown eyes.

- My kids are all born with a head full of dark brown hair and blue eyes. They all keep some shade of blue for their eyes but at 6 months their hair falls out completely and they are bald babies for 6 months or so. Then it comes back in very blonde.

The genetics of eye color inheritance Because of this, it is possible for two brown-eyed parents to have a child with a different eye color than theirs. For two brown-eyed parents to have a blue-eyed child, for example, the mother and father would need to pass on a pair of blue alleles each to their offspring.

- Example: First parent is Bb, second parent is bb, then their children will end up as either Bb, bb, Bb, bb. If both parents carry the genes for brown eyes and blue eyes, then each time they have a child, there is a 25% chance it will have blue eyes. Example: First parent is Bb, second parent is Bb, then their children will end up as either BB, Bb, Bb, bb.

The Genetics Behind Blue Eyes Considering these two genes (B and G), and the fact that people have two copies of a gene (one from mom and one from dad) and that B is dominant over b, G dominant over g, and that the gene B is dominant over G, the genotype for true blue eyes must be bbgg.

Bright Hub Brown, green and blue eye color comes from a pigment called melanin. Brown eyes have a lot of melanin in the iris, green eyes have less, and blue eyes have little or no pigment. Two genes, bey2 and gey, work together to make brown, green, or blue eyes. Each gene comes in two versions or alleles.

- My now 8 year-old son has gone from having brigth light-blue eyes to now green eyes. The change in his eye colour started from approx. the age of 6 years old. His father and I both have blue eyes, so we are baffled. There are no green eyes in our immediate family.

How Late Can My Babyâs Eyes Change Color? Babies are usually born with blue/blue-gray or brown eyes. If both parents are light-skinned Caucasians, blue or blue-gray may be the eye color you will first see. If you both have dark skin and brown eyes, your little one will probably have brown eyes at birth, but not necessarily. It depends on the genes for eye color that you passed down to them. { MORE:Top 10 Tips for Choosing a Pediatrician for Your Child } Eye color is inherited. It used to be thought that it was a simple inheritance pattern, and often it is. Brown eyes are dominant over blue eyes. Research has revealed that there may be more than two genes involved in eye color as it was previously believed. If you have brown eyes, you might have multiple brown-eye genes, or some brown and some blue.

Eye color: The myth Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.ye color: The myth. One of the oldest myths in human genetics is that having blue eyes is determined by a single gene, with the allele for blue eyes recessive to the allele for non-blue eyes (green, brown, or hazel).

- You would have to say, Are Brown eyes a recessive or dominant gene over blue eyes. If you are … asking if being Tall is recesive or dominant, it is multifactoral. So if your parents are tall, chances are you will be tall. If they are short, chances are you will also be short.

Is it true that all babies are born with blue eyes? The truth. First of all, it’s definitely not true that all babies are born with blue eyes. Babies of African American, Hispanic and Asian descent are usually always born with dark eyes that stay that way. This is because these non-white ethnicities naturally have more pigment in their skin, hair, and eyes. The specific pigment is called melanin, and it’s more abundant in darker individuals.

Can a baby have blue eyes if the parents both have brown eyes? The gene for brown eyes is dominant, so if each parent had one BROWN gene and one BLUE gene, they'd both have brown eyes themselves, but could easily pass on blue eyes to their children (about 25% of the time). Simple genetics. Source(s): 4-year college degree in Biology/Genetics. Jill P · 5 years ago.

Will my baby's eyes stay this color? Caucasian babies are often born with steel gray or dark blue eyes; they may stay gray or blue or turn green, hazel, or brown by the time they're 9 months old. That's because a child's irises (the colored part of the eye) may gain more pigment in the months after she's born, but they won't get lighter or more blue.
