yes.
Your boyfriend has a dominant trait-brown eyes- which means he also may also carry a gene for a trait that he himself does not posses-otherwise known as being a "carrier." The word Dominant does not suggest that "oops he has brown eyes so its over, all of our kids will too" it simply means that while he may have a brown eye gene and a blue eyed gene combination, the brown eyes are what he displays. Thus "dominance." Any Children however that inherit his brown eyed gene will also have brown eyes.
You have blue eyes which is a recessive trait, so the gene you carry but may not display also has to be a reccesive trait.
it's easier to explain with a visual but thats impossible, so let me try and show you how it would work.
We don't know what your bfs non-showing trait is so lets assume for the sake of argument that it is blue.
We also don't know for sure that your non showing trait is blue, it could be green, but lets stick with blue here too.
your boyfriends gene pair looks like this:
Rr (1 dom. 1 reccesive)
and yours looks like this:
rr (two reccesive)
So taking one gene from you and one from him (a child gets one gene from mom and one from dad for every trait they posses) your childs gene pair possibilities are this:
Rr, Rr, rr, rr
in other words a 2 in 4 chance or 50% chance of having blue eyes
This is a 50/50 chance PER CHILD, not a 50/50 chance combined for all your children.
remember that we dont know for sure what your non-active traits are so while this model is accurate whereas genetics are conscerned, it may not be acurate to your specific case, i was simply using it as a "teaching tool"
Also, there is always the possibility that his non-active trait is still brown, in which case, yeah, your screwed for the idea of having blue eyed kids, (but the good news is that they'd have a reccesive blue eyed gene from you, so your grankids could have blue eyes) . That is pretty uncommon though. Most dominate trait people carry some reccesive gene.
hope this helps and didn't confuse you too much!

Blue eyes are dominant whereas Brown eyes are recessive. So if you have blue and your husband has blue, then there is a incredibly high chance that the baby will have blue. If your husband has brown eyes, then there is a 25% chance for brown and 75% chance for blue.
In my family my father had blue, mother brown. Me and my next 2 sisters had blue, my last sister had brown.

You have two blue eyed genes in order to have blue eyes, so you baby will get a blue gene from you. You'd have to look at your boyfriend's parents to see if there's a possibility that he has a blue eyed gene that doesn't show up in him because brown is dominant. If one of his parents has blue eyes, then he does and he has a 50/50 chance of passing it on to your child. He could still have gotten a blue gene from a parent even if that parent didn't have blue eyes as long as one of the grandparents did. If he passes on his brown gene, your baby will have brown eyes.

It depends upon whether or not your boyfriend has a recessive gene for blue eyes.
The gene for blue eyes is recessive, which means it only surfaces when one has two copies of it (one from each of your parents). Since you have blue eyes, we know that you have two copies of it, so the eye color of other members of your family isn't important.
What is his family like? Do either of his parents have blue eyes? If so, he is carrying a recessive gene for blue eyes, and it possible for you to have a blue eyed child.
If neither of his parents do, do any of his (full) siblings, or his grandparents, have blue eyes? If so, it is still possible (but uncertain) that he is carrying a gene for blue eyes.
For more knowledge, here's an introduction to Mendelian genetics:
http://en.wikipedia.org/wiki/Mendelian_genetics
Also, what on earth does your skin being "porcelin and very soft" have to do with the question?
It is tempting to say that, no, of those people with blue eyes, only those with tough skin have any chance of bearing blue-eyed children with a brown-eyed husband.

It's possible, if your boyfriend has one gene for blue eyes and one for brown. But if he has two genes for brown, your baby will definitely have brown eyes, although probably carry one gene for blue. Brown is dominant and blue recessive, which means that one brown gene and one blue will give brown eyes. Two brown will also give brown eyes, and two blue will give blue eyes.
So without knowing whether your b/f has one or two brown eye genes, your chances of having a blue eyed baby are 1 in 4. If you know your b/f has one blue and one brown gene, your chance is 1 in 2. Do any of your b/f's parents, siblings, etc. have blue eyes? This would mean he might have one blue eyed gene.

You sound like you could be my daughter's mom.... I have olive skin, dark brown hair and eyes.!
Of course there is always a chance your baby could have your eye color.
I have very dark brown eyes, my husband has green eyes and our daughter has sky blue eyes (our two boys have dark brown eyes like me). My dad is the ONLY one in my family with blue eyes and my husband's mom had blue eyes too.
While brown eyes dominate, it is possible for blue to pop up.

Yes, my children have most of my physical traits, except my eye color, they have blue eyes like their mother. The only other person in my wife's family to have blue eyes was one sister and her grandmother. So yes it is possible. But don't be mad if they are not blue either.

There is a chance that your child will have blue eyes , however don't be overly excited if when your baby is born and they have blue eyes , many babies are born with blue eyes and then they change . but good luck and i hope you are blessed with a beautiful healthy child
