Bateman’s principle

In most cases, it is the male’s secondary sexual traits that are exaggerated.

This shows that sexual selection is more common and intense on males than females

#Unit 11. Evolution and Behavior

Bateman put several males and females together in bottles for several days. 
He concluded that the number of offspring sired by a male increased in proportion to the number of females he mated.
In contrast, the number of offspring produced by a female did not increase with the number of males she mated.

Monogamy

Each individual mates exclusively with one partner over at least a single breeding cycle and sometimes for longer.

Monogamy occurs in fish, amphibians, reptiles, and mammals, but it is only commonly observed in birds, some rodents, and a few primate species.
