Question

Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system?
1. Male stalk-eyed flies form leks where receptive females come visit
2. Male Neotropical giant damselfly defend water-filled tree holes, which are the oviposition sites for females. Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites.
3. Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime.
