Mothers: 1, Genes: 0

New Scientist is carrying this article summarizing a new study in Rhesus monkeys that seems to confirm the results of a similar study in humans: mothering trumps genes. Careful study has revealed that children are much more likely to be aggressive and antisocial if they have a "short" version of a specific gene. However, both studies have now confirmed that the gene only "expresses" itself when the infant is reared in an abusive home.
So be sure to call your mom and thank her... she's the only one who kept you from growing into a homicidal maniac!

Funny, I haven't heard from you or your brother since reading that article. lol
makes sense - I've always thought that genes will predispose you towards a behavior, but that you still have choice in the matter. Awhile ago, someone did a study of siblings and homosexuality. It seems that if one sibling is homosexual, 10% of the others are - goes up to 20% for fraternal twins and 50% for identicals. Now, mind you, this study is about 10 years old and I'd have one hell of a time finding it, but it does lend credence to this finding.
