I certainly hope we can distinguish between a professional opinion and lay opinion in regard to genetic information. Your dentristry agains my law doesn't put either one of us in a very good position to render professional opinions about the transference of genetic abnormalities from parents to children.

I remember your example from my undergrad bio 100 years, but I also remember that a) diseases (or any phenotype characteristic) aren't likely to be caused by one single gene, b) Punnett squares are heuristic devices for understanding how genes cross from parents to offspring--unless you've got the genetic structure mapped, they aren't going to give accurate statistical represenations of a given genepool, and c) the human genome is a lot more complex than that of a pea.

useful for teaching students about different colors of roses
understanding visible genetic abnormalities in human beings? not so useful
