I didn't make any claims at all. I merely said the person had no info to base their claim. They were the one who automatically leaped to the conclusion that it was probably genes.

It wouldn't necessarily make the gene theory stronger. It would depend on if the defect is a dominant or recessive trait, and if that family indeed has the trait in their background. None of which they know.

Smoking causes cancer. A person and her siblings contract a cancer that is known to be caused by tobacco smoke overwhelmingly more often than any other factor. I just don't' see the automatic, obvious leap to the conclusion that it was probably genes.

Edited because I realize I was responding to the wrong poster.
