When patricia was six months pregnant with her first child, darin, her doctor gave her testosterone to prevent a miscarriage. patricia's second child, chaz, was given shots of testosterone when he was six years old. assuming all other things are equal, how aggressive will these two boys be when they are?

Darin is likely to be more aggressive than Chaz.

The likely reason why Chaz is given testosterone shot after he's born is because he had some sort of genetic defect that cause him to have lower testosterone level compared to normal. Which means that chaz much more likely to display less aggressive behavior compared to Darin.
