Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
In the words of James Madison: “The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may justly be pronounced the very definition of tyranny.”
Within the separation of powers, each of the three branches of government has “checks and balances” over the other two. For instance, Congress makes the laws, but the President can veto them and the Supreme Court can declare them unconstitutional. The President enforces the law, but Congress must approve executive appointments and the Supreme Court rules whether executive action is constitu-tional. The Supreme Court can strike down actions by both the legislative and executive branches, but the President nominates Supreme Court justices and the Senate confirms or denies their nominations. “Ambition must be made to counteract ambition,” wrote James Madison in Federalist 51, so that each branch will seek to limit the power of the other two branches to protect its own power. Such a system makes concerted action more difficult, but it also makes tyranny less likely.
