There’s no way to tell (as far as I know) if she has BB or Bb.

If one of her parents has blue eyes, then you know she’s got one recessive gene for blue eyes. My mom had blue eyes, and when I married a blue-eyed guy I figured we had a 50-50 chance of having a blue-eyed child. We got lucky – both our daughters have blue eyes.
My wife has blue eyes and I have brown eyes. Blue eyes are evil and I am thrilled that my daughters don’t have them. I DOMINATE!
One Australian news site captioned this story “Blue-eyed people ‘inbred mutants’”.
I guess that makes me the daughter of an inbred mutant. I wonder if this means I have a super power?

That’s how I understood it. I guess I have the recessive blue eye gene.
My mother has blue eyes and my father has brown. My sisters and I all have brown eyes.
My ex-husband is also brown-eyed, with a blue-eyed mother, and we produced a blue-eyed child.

Yup. There is a most recent common ancestor (MRCA) of all surviving humans. And that’s just the most recent common ancestor - there may be several common ancestors further back in time (e.g. the one with blue eyes).The MRCA is usually thought to have lived in Paleolithic times, but some estimates put them in historical times:

I thought they had tracked back to the MRCA woman that all women are related to and the MRCA man that all men are related to? Then the big joke is that the MRCA woman was way before the MRCA man, so there was a time of, as Stephen Fry put it (on QI) “heavy to industrial strength lesbianism” Of course, this joke require a tremendous lack of knowledge about biology, but it is sort of funny.
I have green eyes. My husband has brown eyes. Both our mothers had blue eyes. We produced a bb blue-eyed kid.
Both of my parents have brown eyes, but they each had one parent with blue eyes. I’m the only blue-eyed one of 5 children. Plus I have one blue-eyed and one brown-eyed daughter.
So, welcome to the extended family!

guizot, to answer your question, I had to remember back to what I learned about it in biology.

This was explained in a thread I started years ago.
Anyways: My mom has brown eyes, dad blue. I have brown eyes, my husband blue: kid has blue eyes. Apparently there was a 50/50 chance of that happening. She’s got my dad shade of blue though (blue with yellow speckles), not my husband’s (all blue).

Whoosh? Prof. Hans Eiberg?
How far does eye color extend through the generations?
Two of my grandparents had blue eyes and two had brown. My father has green eyes and my mom has blue eyes. My brother and I both have green eyes.
My daughter has blue eyes and so does my husband and both his parents.
Blue eyes here.
I have blue eyes but they change color and there’s always brown rings around the pupil, so I bet I’m like the one outlier they mentioned in the article. Maybe.
How can they conclude that there was just one person who passed on the mutation, though? There are all sorts of genetic, um, differences, that crop up in the children of people who aren’t related. Why was blue eyes more likely to have been passed along by a sole individual than Syndactylism or red hair? If the mutation is possible, it seems like there’d have been more than one person who “first” aquired it, just as with other mutations, particularly one that has proven to become so commonplace.
I didn’t know until I read that article that blue eyes is so rare (apparently).
Explain yourself, young lady!

Everyone has two chromosomes and the trait for blue eyes–let’s call that a little b. So b, then.. The trait for brown eyes is usually depicted as a large B.
There are three combinations a person could have. They’d either have a BB, Bb, or bb. Only a combo of bb chromosomes would make blue eyes.
If you have blue eyes, you have bb. So you can ONLY give a small b to a child. Your SO, however, if she has brown eyes, might have be BB or Bb. Bb means she CARRIES the trait for blue eyes, but she wouldn’t have blue eyes since that one large B is dominant. So if you had four kids (and she is Bb), the chances that one of them (or two of them) would have blue eyes are fairly good.
However if she carries the BB genes, there is no way any of your kids would have blue eyes. This is because they’d get a b from you, but a B from her..making their chromes Bb. So they’d carry the trait for blue eyes, but they’d have brown.
There’s no way to tell (as far as I know) if she has BB or Bb.

This is how it works if you actually only have the 2 genes. The Cherokee people, however, have a dominant blue eye gene, with the brown being a recessive gene. This is how – with a father who was 1/4 Cherokee and had the most amazing blue eyes with gold flecks, and a mother of Austrian/Prussian descent with eyes so pale blue they almost looked white in the right lighting – produced 1 child with brown eyes, 1 with blue and then me. My eyes are somehwere between brown and green, but run the gamut from black to turquoise – and have blue specks in them.
My children (I have the eyes mentioned above) both have blue eyed fathers. I have one blue eyed child (well, hers run the gamut from grey to ice blue to pale green) and one very much brown eyed child.
What I wonder is am I related to all ya’ll blue eyed people since both my parents were blue eyed or does my having dark eyes somehow negate that whole “all blue eyed people share a common ancestor” theory?
[QUOTE=Harmonious Discord]
Don’t they already claim that everybody is related after so many generation’s back?
[/QUOTE]
What other possibility is there? Not only every human, but every living organism on the planet, plant or animal.
I’ve got dark blue eyes, like my mother.
: peeks in and waves to all her rellies :
If I admit I have blue eyes, I don’t have to add you all to the Christmas list, do I? Because if so, y’all need to know things are going to be really tight this year.
Christmas list? Heck, I can’t even add y’all to the Christmas CARD list. But I have really blue eyes, my daughter’s are a grayish-blue, and my son’s are a deep, almost navy blue with little flecks…I really need a good picture of them! And my sister has blue eyes.
Gray eyes here, so I’m related to all of you.
I think my niece will have blue or gray eyes when she grows up. My sister and her husband both have hazel eyes, but she’s a year and a half now, and her eyes are still blue. I think she’s going to look a bit like me, poor kid…
Mr. Neville’s related to all of us, too- his grandfather had blue eyes.
