Polygynous

In polygyny, one male mates with more than one female in a single breeding season, but females mate only with one male.

In species with male-male competition, males are often substantially larger than females, a phenomenon called sexual dimorphism.

Condition favor polygyny

Resource-based polygyny - Choosing dominant males, a female may be gaining access to good resources.

Harem mating structures - Sometimes males defend a group of females without commanding a resource - based territory. 

Ex- horses and zebras, some deer, lions, and seals.

Communal courting - In some instances, particularly in birds and mammals, males display in designated communal courting areas called leks.
