To simplify: the blue eyes gene is mostly thought as a recessive gene, yes. The reason why only a few would have it in a family is the same reason for why you all look different. Parents have several sets of genes and they give them to their children randomly. Different combinations happen and start to formulate. [ Now he has a little more information on it!]

It is as you said. There is quite a bit of new development that has happened in the two decades that I've been confided in the chair. And I'll be honest, this place looks quite a bit better about it than the world where I come from. I can only hope our technological and social development will continue to travel along these similar paths.
