Final answer:
Social mating systems in animals include monogamy, polygyny, and polyandry, wherein monogamous pairs mate for a season, polygynous males compete for territories to attract females, and polyandrous females mate with multiple males.
Step-by-step explanation:
When discussing 3 social mating systems, we refer to the innate behavioral strategies animals use to reproduce. The first system is monogamy, where one male pairs with one female for at least one breeding season. This is often seen in bird populations where both parents provide care for offspring. Polygyny is where one male mates with multiple females. Males typically compete for territories providing valuable resources to attract females.
For example, the yellow-rumped honeyguide males defend beehives to attract wax-feeding females. Lastly, polyandry involves one female mating with several males. Although less common, this system ensures genetic diversity and may occur when females are able to control more of the breeding resources. This is the required answer.
