is there any chances of 2 people that one has blue eyes and the other has brown,having a blue eyed baby?& why?

Answer 1

Yes, I have brown eyes and my husband has blue eyes and our son has blue eyes. It is pretty complicated. Researchers used to think that brown was always a dominant color but it is a lot more complicated than that. It has to do with your parents, his parents, and a bunch of different hereditary factors. Here is a link that explains it better.

Answer 2

Sure.
According to what I learned in biology, blue is a recessive trait, meaning it came from a blue gene from both parents. Brown is dominant, meaning one parent gave a brown gene for sure, but it's uncertain what the other gene they carry is-- it could be brown, green, or blue. So there is a chance the baby could get blue eyes, but only if the brown-eyed parent has a hiding blue eye recessive gene....
But-- a friend has brown eyes while her parents, respectively, have blue and green eyes. I asked my college science teacher how this could be and was told that it might be a cumulative sort of thing-- where it's like a build-up of color, you might say.
Either way (whichever genetic theory is true) it is possible to have a blue-eyed child.
How do I know for sure? My half sister has blue eyes (like her mother, I think) but our father has brown eyes! Cool, huh?

Answer 3

yes. In simple terms, you could have the blue eyed gene too, but brown is dominant over blue, so you got brown. Your husband would have only blue eyed genes if he has blue eyes (or vice versa). So, if the gene you give to the baby for eye color is blue, then the baby can have blue eyes. If you send the brown gene, then it will have brown eyes. (eye color isn't quite this simple, there are some other factors, but this is basically how it goes.)

Answer 4

Blue eyes are a recessive gene, which means that for your baby to have blue eyes, both you and your husband need to carry the "blue gene." Obviously, if you have blue eyes, then you are a carrier but look at the brown eyed person's family...are there any blue eyed people? If they are all brown eyed, then chances are very slim. It gets much more complicated than that, if you are really curious then www.wikipedia.org has a very good explaination of how recessive genes work.

Answer 5

If I understand your question correctly, the mother and father both have Heterochromia (Heterochromia is the presence of different colored eyes in the same person). Most cases of heterochromia are hereditary, caused by a disease or syndrome, or due to an injury. Sometimes one eye may change color following certain diseases or injuries.

Specific causes include:

Familial heterochromia (autosomal dominant transmission)
Waardenberg syndrome (congenital and autosomal dominant)
Some medications used to treat glaucoma may cause the iris (colored part of the eye) to darken
Neurofibromatosis (may cause the affected iris to darken)
Injury, hemorrhage (bleeding), glaucoma, or foreign body in the eye.

Based on the above, the cause of the heterochromia would need to be determined in order to find out if it is a trait that would be passed on genetically. Even so, if the gene that causes the heterochromia is a recessive gene (meaning not a dominant gene), I would say there is a chance that the child would have two matching eye colors, and probably would just carry the gene for heterochromia.

Answer 6

I think it's really just a 50/50 chance. I have blue/green eyes and my husband has brown eyes. Everyone in my family has colored eyes and everyone in my husbands family has brown eyes...our son has brown eyes. I'm pregnant with second baby now and i can't wait to see what color her eyes will be. Hopefully blue like mine!!

Answer 7

My husband has dark brown eyes, and I have green eyes, yet our 8 month old son was born with blue eyes, the most beautiful blue eyes, and one of his eyes has one streak of brown in it. So it just goes to show you that it doesn't matter what color your eyes are, it's all what runs in the family. (Almost my mom's whole family has blue eyes) I can't answer why though, sorry.

Answer 8

Yes it just depends on who has the dominant genes. My husband has brown eyes and I have blue/green eyes and both of our sons have blue eyes.

Answer 9

I have the darkest eyes imaginable, almost black. My wife has blue eyes. We have had 2 children (both girls), and our oldest has brown eyes, while our youngest has the prettiest blue eyes i've ever seen. So yes, it is very possible to accomplish that. You just don't know if it will happen or not.

Answer 10

My mother has blue eyes and my dad's are black. The oldest has hazel eyes, the next two green, and the last 2 brown.
