Final answer:
The system that uses the same terms for parents and aunts and uncles, based on gender and generation, is the generational kinship system.
Step-by-step explanation:
The kinship system that organizes people by gender and generation, and uses the same terms of address for father and mother as well as aunts and uncles, is known as the generational kinship system. This system distinguishes kinship terms only along gender and generational lines, and thus has the least complicated kinship terminology of all kinship systems. Generational kinship greatly expands the family of orientation to include all kindred within the same generation, serving as a societal structure that creates large and powerful family networks with significant roles, rights, and responsibilities.
