Your knowledge of genetics is analogous to an astrologer's knowledge of astrophysics. But I suppose you are not alone among those duped by PBS-level junk science.
Genetic inferiority has nothing to do with criminal behavior. Genetic inferiority has to do with birth defects and congenital diseases. I know plenty of fine, upstanding people who have inferior genes. I have diabetic, epileptic, and cancerous friends, as well as some with Down's syndrome and other genetic anomolies. None of them are rapists or criminals.
On the other hand, many criminals are stronger and smarter than average. They in fact have superior genes.
Genetic quality is irrelevant with regard to criminal behavior. Educate yourself or shut your ignorant, bigoted mouth.
