In many societies, socially stratified marital relationships are preferred within their own layer. The opposite is the anisogame marriage ( "not equal " ), in which one spouse is in a higher ranking caste, class or layer " marries up ".

Like all rules of marriage is the isogamy in two versions:

• As a favor ( preferentially ): Status equality is only recommended, but spouses of different status experienced no rejection or change their status;
• As a rule ( prescriptive ): Status equality is required as a condition of a marriage.
