Can you tell me in human beings, brown eyes are usually dominant over blue eyes. Suppose a brown-eyed woman whose father had b?

Eye color: Is genetically complex with a number of factors that determine the actual color appearance. However the brown gene is dominant and the blue gene is recessive. Since only one dominant gene is required for brown eyes, then brown eyed parents can produce blue or brown eyed children, while two blue eyed parents should produce only blue-eyed children. ...Read more

Sister has brown eyes, other two siblings have blue eyes. What gene is dominent?

Sister has brown eyes, other two siblings have blue eyes. What gene is dominent?

Brown over blur: The inheritance of eye color is somewhat complex but when it comes to brown v. blue --- brown is dominant over blue. In your family, Mom and Dad probably have brown eyes but carry one gene for brown and one for blue. There is a 25% chance of a child in this mix with blur eyes. All other combinations will be brown. It is a matter of statistics. ...Read more

Could blue eyes be dominate over brown?

Could blue eyes be dominate over brown?

Generally not: Brown eyes dominate over blue. While eye color inheritance is somewhat mixed, if the only colors in question are strongly blue and strongly brown, then brown dominates. This means of the two genes for any one characteristic, in this case brown, if you have one brown (the other can be either), your eyes will be brown. You would require two blue genes to get blue eyes. ...Read more

I learned that behind brown eyes are blue eyes. Is that true?

No: Eye color is the result of a complex combination of the location and amounts of pigment in the iris. The thickness of the iris has an effect as well. ...Read more

Do people with blue eyes generally have worse sight than people with brown eyes?

Do people with blue eyes generally have worse sight than people with brown eyes?

Not at all: Iris color is determined by the amount of brown pigment it contains. A large amount creates brown eyes; less pigment creates a blue appearance. Eye sight is related to the shape of the eye and health of the retina (film layer) and optic nerve. Some eye conditions can lead to poor vision and blue eyes (ocular albinism), but eye color itself is usually not related to eye sight. ...Read more

Can you tell me if I could have a child with green or blue eyes even though I have dark brown eyes?

Can you tell me if I could have a child with green or blue eyes even though I have dark brown eyes?

Yes: Your eyes require only one brown dominant eye color gene to make you brown, leaving room for a green or blue recessive gene in your mix. Dad would need to have a similar recessive gene to add, but these are possible. ...Read more

Could you tell me if my wife has blue eyes, and I have brown eyes, can our child still have blue eyes?

Could you tell me if my wife has blue eyes, and I have brown eyes, can our child still have blue eyes?

Possibly: The brown eye gene dominates over blue so all blue eyed people have 2 blue eye genes. Your wife will only pass the blue gene to her offspring. As a brown eyed male, you could have one blue and one brown or two brown genes. If you only have brown, your kids together should have brown eyes. If you have a blue and a brown, you could have a blue eyed kid. ...Read more

When I was a baby I had blue eyes, as I grew up they turned green, and now I'm 18 and their slowly turning brown, I want to keep them green, how?

Sorry: The color of the iris is determined by your genetics. The iris is inside the eye and cannot be modified without harm to the vision. If you want different color eyes, the only way is to pick out a colored contact lens to wear over the front of the eye. ...Read more

Does people with blue eyes wear glasses more than brown eyes?

No Known Assn.: Visual acuity that can be improved with glasses often relates to the shape of the eyeball which is, as far as is known, not associated with eye color.
The genes which determine eye color are being worked out: http://www. Sciencedirect. Com/science/article/pii/S0002929707000407 and may have some weak association with risk of melanoma. ...Read more

Does latisse (bimatoprost) cause blue eyes to turn brown?

Yes it can: Latisse (bimatoprost) is in the postaglandin analogue drug class. These drugs were invented to treat glaucoma by lowering eye pressure. Side effects growth of eyelashes, red eyes, and redness of the eyelids. They can also cause reactivation of herpes virus in the eyes, leading to inflammation and loss of vision. Long term use can cause increased pigmentation of the iris, making blue eyes brown. ...Read more

Blue eyes on a kid with 2 brown eyed parents. How is this possible?

Blue eyes on a kid with 2 brown eyed parents. How is this possible?

Easy one: Brown gene dominates over blue so parents only need one of 2 genes to be brown. Blue eyed infants must get one blue gene from both parents, so in this case both parents carry one blue gene. Nothing spooky here, just basic genetics. ...Read more

How can a child have blue eyes when both parents have dark brown eyes?

How can a child have blue eyes when both parents have dark brown eyes?

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. ...Read more

Is it possible to have brown eyed parents and grandparents, and yet have blue eyes yourself?

Is it possible to have brown eyed parents and grandparents, and yet have blue eyes yourself?

Blue requires 2: Dominent genes (a) require only one coded gene from a parent to express a color, while a recessive gene (a) requires a pair. At conception you get genes from both parents. Daddy brown eyes aa or aa donates one (a or a)& mommy brown eyes aa or aa donates the other. The baby could have aa, aa, or aa. If aa then eyes are blue. If you have blue eyes, your brown eyed parents were both aa (carriers of blue). ...Read more

I have brown hair brown eyes, husband has blue eyes blonde hair fair skin, will baby most likely have brown eyes and brown hair?

I have brown hair brown eyes, husband has blue eyes blonde hair fair skin, will baby most likely have brown eyes and brown hair?

Difficult to say: The genetics of human eye and hair color are very complex--you can pin the odds down better the more genetic history of eye and hair color you can obtain--siblings, parents, aunts and uncles, grandparents, great-aunts and uncles. There are odds tables based on this information. Accurate prediction is possible with DNA analysis: 45 mutations in 12 genes for hair color. ...Read more

I have light brown eyes, my mom has blue eyes, husband has blue eyes, blue eyes run in his family what are the chances of our baby having blue eyes?

I have light brown eyes, my mom has blue eyes, husband has blue eyes, blue eyes run in his family what are the chances of our baby having blue eyes?

50% per conception: If both your husband and mother have blue eyes and yours are brown, you are a carrier of a blue eye gene. Your brown gene dominates your blue, so yours are brown, but since dad can only donate a blue gene, your offspring will have 1 blue gene from him and either blue or brown from you. Your kids have equal chance of being blue or brown. ...Read more
