If Israel's laws are not based on race, then clearly apartheid is not the correct term. Particularly as Arab citizens of Israel can vote (Nelson Mandela was particularly cutting about indigenous Australians who claimed they lived in an apartheid situation, pointing to the right to vote and stand as candidates). The analogy you want surely is dhimmi. Except Israel's laws are much less discriminatory than that.

Discriminatory laws are rife in the Middle East (Jordan bans Jews from being citizens, Saudi Arabia bans Jews from entering without special permission) and wider (e.g. German and Japanese nationality law). Why pick on the democracy?
