The answer is "Heritability".
Heritability reflects the way that all people in any types of living things contrast from multiple points of view among each other. The variety (~differences) among people inside a species relies upon both genetic and ecological contrasts. For instance, individuals differ in height.
The similarities between Greek and Roman government were that both favored aristocratic rule, both believed that their citizens should have a right to participate in politics and military service and they both governments were made up of several city states.
The differences were that the Greek government did not have political parties. If a Roman official was unwanted in office, the citizens would vote him off and just be glad that he wasn't governing them anymore, but if a Greek official was unwanted he'd be kicked off, ostracized, and banned from Athens for 10 years. Also, the Romans didn't allow women to vote, but women of upper class citizenship could influence their husband's vote.
