HI! I am no expert or doctor, but from what I have been told and read, it is possible. Less likely, but possible. Repressed genes make this possible. Example: Your whole family has always had blue eyes, but you DO have one great great great grandfather who had brown eyes. There may be no one to have brown eyes again because that gene is repressed, but it can come forward at any time... possiblly in your child.
If you talk to a pediatrician or an ob/gyn they can give you exact percentages and such.
Good luck!
