"One of the dangers of the Genome Project is that it is possible to identify specific genes belonging to a particular group of people. For example, the gene for sickle cell disease is specific to Afridans. Thus, it is possible to create a virus that will specifically destructive to that gene. It can then be released and will cause genocide among the Africans, a sort of biological "smart bomb".

Scary! If there is such technology, and if it fell into the hand of idiots like Ahmad Ismail, I can't imagine how horrible the world will be.
