Anti-social behavior is any aggressive, intimidating or destructive act that destroys another individual's life. Crime is against the public law that has been laid for everyone's safety, but there have always been people who try to breach these laws. As criminal behavior is problematic to an individual as well as to society, it is discouraged by setting punishments as a consequence of the breach. Genes are the basis of heredity and regulate traits like skin color, eye color, stature, etc. What is less clear is whether genetics has an influence on a personality trait or whether it is nature rather than nurture that determines the result. Is this because the individuals were born with the predisposition to behave in an anti-social or criminal manner or has the environment they have been brought up in been the main cause. Seminars typically have significantly fewer students per professor than normal courses and are generally more specific in the topic of study. Seminars can revolve around term papers, exams, presentations, and several other assignments. Seminars are almost always required for university graduation. Normally, participants must not be beginners in the field under discussion at US and Canadian universities. Seminar classes are generally reserved for upper-class students, although at UK and Australian universities seminars are often used for all years.
