Some people say that eye color is more complicated than what is taught in elementary biology text books. But the simplistic answer is that the mother has two recessive alleles — bb. The father is either Bb or BB. If he is BB, then all of his kids will have brown eyes. If he is Bb then the kids have a 50% chance of being bb blue eyes. But the chance of the father being Bb or BB depends on the frequency of the alleles in the population.

Of course, everything is hard to say, because your gene is carrying 3 generations worth of eye color genes. There is no telling which genes you are carrying that have not been expressed. Plus there is no way telling which genes have been passed to your child and which one will be expressed. For example, I have brown eyes and both my parents have brown eyes. My husband has blue eyes and his parents both have hazel eyes. For my children, one has blue eyes and one has slate gray eyes.

I obviously passed down some unexpressed recessive genes to my children and give them light colored eyes despite the fact they have a mother and grandparents with brown eyes. In the way, I suppose mother can only give a child with blue eyes.
