Final answer:
Polygyny is the practice of a man having multiple wives.
Step-by-step explanation:
Polygamy is the practice of a man or a woman having more than one spouse. In traditional societies, such as the Nuer people in Central Africa, it is far more common for men to have multiple wives. This practice is known as polygyny. Polyandry, on the other hand, is when a woman is married to more than one man. It is less common and occurs in about 1 percent of cultures worldwide. The Nuer practice of men having multiple wives is an example of polygyny.
