Final answer:
Monogamous behavior is primarily known in rodents, such as California mice, which form monogamous pair bonds; this is less common in other animal groups.
Step-by-step explanation:
Monogamous behavior, as observed in California mice, is primarily known in rodents. California mice are indeed notable for forming monogamous pair bonds, a phenomenon that is relatively rare among mammals but is seen in some rodent species. Most other animal groups, including primates, insects, and reptiles, tend to display a variety of mating systems, and the presence of monogamy is less common and less well-known outside of avian species. Comparing different species' reproductive strategies, such as that of the Chinook salmon and pronghorn antelope, can highlight the diversity of breeding behaviors in the animal kingdom.
