my wife and i have blue eyes .one of my kids have brown eyes.is this possible?

Answer 1

Brown is dominant. It's more then possible that your child will have brown eyes.

Answer 2

Absolutely, yes.

Blue eyed parents can produce children with brown eyes. It just means that the child had a strong brown OCA2 gene on chromosome 15. Chromosome 15 has 700 to 900 genes. That leaves a lot of room for mixes.

If any other loci were involved, your child's eyes could have been green, gray or hazel as long as it was stronger than the blue.

I have no idea where a lot of these people are getting their psuedo-science from. It's not "rare" or "impossible". In fact, it happens quite a bit.

This is an easy to understand website by a Geneticist from Stamford that explains how and why this happens:

Answer 3

yes any first year biology major can tell you it is possible. Your and and your wife's genes are made up of dominant and recessive traits. So if you had brown eyes and she blue then your children are more likely (not always) to have brown one.

Then there is the thing about RECESSIVE genes. For instance yes both of you have blue eyes BUT you both might have brown eyes recessive genes and this might be dominant. This is very important in many communities such as Jewish and African Americans who may have recessive Tay Sacs or Sickle Cell. If two people have these recessive genes their children might have then an it can be fatal.

The third explanation is also "natural variation"- humans sometimes exhibit new expressive traits- in you child case brown eyes which might better adapt him to the environment. Brown eyes have been shown to have a lower risk of cancer etc...

Answer 4

Yes it is possible, but It is a 1 in 100,000,000 chance. Pretty rare, but read on.


Colored eyes colour is an inherited trait influenced by more than one gene. In humans, three loci associated with eye colour are currently known: EYCL1, EYCL2, and EYCL3.These genes account for three phenotypic eye colours (brown, green, and blue) in humans. Although it was once thought that brown eye colour was always dominant and blue eye colour was always recessive, the fact that two blue-eyed parents can give birth to a brown-eyed child has shown that the determination of eye colour does not follow the simple rules of Mendelian inheritance, although this is so rare (perhaps 1 in 100,000,000) that it was not noticed until recently. (Whereas two brown-haired parents having a blonde-haired child is a straightforward example of a recessive trait; the genes for blonde and brown hair are located on the same gene pair.) Eye colour is demanding, as all four genes must determine the same colour for the eye colour to be pure; otherwise a mixed colour such as blue-green will result. Eye colour usually stabilizes when an infant is around 6 months old.

Answer 5

Yes it is possible. What you look like is based on genes. There are Dominant and Recessive genes. How the genes pair up during embryonic and fetal development determines things like eye color, hair color, and even whether or not a person will have a disease such as Sickle Cell Anemia.
As an example: both my parents have brown eyes and I have blue eyes (my great grandmother had blue eyes).
Another example: my husband and I have dark hair, yet our daughter is blonde (my husband's mother is blonde).
You can't just stop and look at the characteristics of mother and father; you must also consider the entire family line.

Answer 6

GeneTree Eye Color Inheritance Chart:
conclusions based on this theory:

2 'light blue' eyed parents cannot have a 'blue' eyed (or darker eyed) child.
2 'blue' eyed parents can have a 'Blue-green' (or lighter) eyed child, but not hazel or anything darker.
2 'blue-green' eyed parents can have a 'Light brown' (or lighter) eyed child, but not brown or anything darker.
1 'Light brown' eyed parent and 1 'blue-green' eyed parent can have a child with any of the possible eye colors.
2 'dark brown or black' eyed parents can have a child with any of the possible eye colors (but it is unlikely they will have a light eyed child, such as light blue or blue).
NOTE: Eye color usually starts out much lighter at birth, and becomes its true color in 1 or 2 years after birth. Also, variations can also occur, randomly, causing deviations from the above conclusions.

just google for eye color calculator there is a free site

Although this theory is very old, originating in the late 1800's, it still is useful in demonstrating; 1) how inheritance patterns were pretty well understood (by some) back then, and, 2) that eye color is, still today (even with the human genome sequenced), very difficult to predict due to its polygenic inheritance pattern.

Answer 7

Does the mail man have brown eyes? Just kidding. Without getting to scientific, brown eyes are a dominant gene and blue eyes are a recessive gene. The odds are greater for a person to have brown eyes.

Answer 8

Yes, if there are people in either of your families who have brown eyes. By the way, brown eyes are the dominant gene, and blue eyes are the recessive gene. So basically, you and your wife just lucked out by having blue eyes. You two are kinda in the minority, so to speak. Hope this helps.

Answer 9

Not 100% sure, but I always heard that parents with brown eyes can have a child with either colored eyes. Parents with blue eyes can only have blue eyed children. Hope I'm wrong on this. Interested in learning the correct answer.

Answer 10

Yes it is possible. It just means that you and your wife had the gene for brown eyes but it was recessive instead of dominant. Your dominant gene was blue eyes. You both passed on the brown eye gene to your child so the only gene he/she has is brown eyes so that is what showed up.

Answer 11

yeah, strange combinations can happen. You must have someone in your family that had brown eyes. It doesn't have to be you or your wife. My husband is hispanic and I'm scandinavian decent. Our kids turned out very light skin, blond hair and blue eyes, my older daughter's eyes slowlyl turned to hazel over the years. But I was amazed because I have always heard that the dark colorings are dominate. It just didn't happen in this case.
