Final answer:
Polyandry is a unique mating strategy where one female mates with multiple males, unlike polygyny, where one male mates with numerous females.
Step-by-step explanation:
Polyandry is a special mating strategy where one female mates with many males. This system contrasts with polygyny, where one male mates with multiple females. In polyandrous mating systems, females often establish territories separate from other females and attract males to the resources they control, leading to several males being drawn to a few females with rich territories. An example of polyandry in the animal kingdom is seen in species such as seahorses and pipefish.
Polygyny, on the other hand, might involve resource-based competition where males vie for territories with rich resources to attract females. This form of mating is observed in species like the yellow-rumped honeyguide, elephant seals, and is also characterized by lek mating, where communal displays by males attract females who then select their mates from among these displays.
