Pat K While it is unusual, it is possible for two blue eyed parents to have a brown eyed child if both parents have a dominant gene for blue and a recessive for brown
that does not exist. Read in wikipedia or elsewhere...
ok, I have read it, and it is probably as usual as albinism. So, maybe not impossible, but very, very, unusual
so….my son-in-law is a brown eyed child of 2 blue eyed parents and in every other way is the image of his father. It is possible but rare. There is a rare recessive brown gene.
Yes it is possible, but involves a scenario as shown in this article. Don would have known this as an expert, but Gene taught a less complicated version to medical students and this Rosie's mom did not realize...

I've read it and a few other ones after the book. Did you notice none of those articles tells you what are the chances to get such a "defect" gene? It must happen once every ten million babies or something like that. I remember reading something more than 30 years ago written by a Nobel prize of Chemistry, I think, who said -it could have been an ol magazine, from the 1950s- that there had been a few occurrences of brown eyed babies from blue eyed parents with wives whose fidelity could not be doubted and there should be a reason, a scientific one, to be discovered. But obviously, it is about a few cases in the world...
My son and his wife both have brown eyes. I have blue eyes and my daughter-in-law's mother has very vivid blue eyes. Her dad has brown eyes. My son & DIL have 2 children with their maternal grandmother's eyes and one child with brown eyes.
