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.

In conditional specification the array of interactions it has with its neighbors, which may include: 

cell-to-cell contacts (juxtacrine factors)

secreted signals (paracrine factors)

physical properties of its local environment (mechanical stress)
