Types of Assimilation. Cultural Assimilation- When two cultures influence one another. May have different customs and/or traditions.. Examples? Past and Present . Religious Assimilation- When converting two religions customs and/ or traditions to create one uniform faith. Or adopting customs from one religion to another. 2: Racial and Ethnic Relations.
