Final answer:
Jealousy in polygynous societies is often managed through cultural norms and structures such as separate households for each wife, rotation systems, wife hierarchies based on seniority, and economic cooperation.
Step-by-step explanation:
In societies that practice polygyny, jealousy between co-wives over perceived unequal attention from their shared husband is often avoided, or at least reduced, by established structures and cultural norms. These structures may include each wife having her own household, a rotation system for the husband's attention, hierarchical arrangements based on seniority, and economic cooperation among the wives. The practice of polygyny is more than just a marital arrangement; it has implications for familial labor, social status, and political and economic alliances. While polygyny is accepted in many societies, it is actually practiced by a relatively small percentage of the population, often by older, wealthier, and higher-status men. As societies undergo urbanization and individuals gain greater access to education, media, and technology, the prevalence of polygamy tends to decrease.
