Sexual behaviors can be strategies to ensure that parent has conceived cared-for offspring. For males, sexual selection can involve keeping other males away from females, to prevent reproduction. Males can transmit more genes if they produce more females, rather than males.

In many species, male pattern and behavioral displays lure females. Displays are fewer if food is scarcer or predators are more numerous.

females
