The perpetuation of a family's genes happens when people have children, and the perpetuation of oppression occurs when one dictator after another seizes control of a country's government. When something is made to last longer or is continued, some kind of perpetuation is going on. Both the noun and related verb perpetuate come from a Latin root, perpetuus, which means "continuous or universal."
