In short, not likely at all, but eye colour is a result of the interplay of four sets of genes, so it's not that simple to determine.

For a simple predictor, have a look at this:

Yes.

If both parents are heterozygous for blue eyes, that is they have one blue eye gene and one brown eye gene then their offspring have a 1 in 4 chance of having brown eyes as each parent only passes on one of their genes to the child.

Yes, but even scientists don't know how or why.

I would have thought it was possible too, my granddaughter has two brown eyed parents and has blue eyes so it should be possible the other way round too
Stop Worrying ?
claireyfairy is wrong. If a parent had one blue gene and one bron gene their eyes would be brown not blue.
Clairey will one blue and one brown gene not give brown eyes though as the blue gene is recessive?
aka pixi is wrong. It won't work the other way round becuase bwon is a stronger gene than blue so if you have a brown gene your eyes will be brown no matter what colour the other gene is.
excuse my spelling, I have had tonsilitis. I think it has ****** my brain a little.
No. In my human biology class (some time ago now) It was explained to me that brown eyed parents can have a recessive gene which enables brown eyed (or mixed blue/brown) parents to produce both blue and brown eyed children. But as blue eyes are made up of recessive genes blue-eyed parents can only have blue eyed children. If it was possible to produce a diagram to make it easier to understand I would.
hmmmm I always get confused which allele is dominant and which is recessive with eye colour. But then you always have the involvement of mutations. Mine are green, product of a genetic mutation.
many babies are born with blue eyes regardless, and this may change to brown later
