Final answer:
Serial monogamy in postindustrial societies refers to individuals who marry one spouse at a time in a series of monogamous marriages throughout their lives, contrasted with polygamous practices.
Step-by-step explanation:
In postindustrial societies, serial monogamy describes c. individuals having consecutive, sequential spouses. This form of monogamy involves adults forming a monogamous marriage with one spouse at a time and may transition through a series of such marriages over their lifetime. Traditionally, this pattern emerges as individuals marry, divorce, and then remarry.
Contrary to serial monogamy, polygamy represents a form of marriage where an individual has more than one spouse simultaneously. Specifically, polygyny relates to a man having multiple wives, whereas polyandry refers to a woman with multiple husbands. In many cultures, monogamous unions are the norm due to various sociocultural constructs and economic strategies.
