each branch of government does not have power over the others.
only one branch of government maintains power over the others.
each branch of government has the ability to limit the power of the others.
no branch of government has a separate power from the others.

Explanation:

Checks and balances is a system in government where each branch (executive, legislative, judicial) has powers to restrict the actions of the other branches, preventing any single branch from becoming too powerful. This matches the definition of mutual power limitation between branches.
