Detailed explanation-1: -Three general mating systems, all involving innate as opposed to learned behaviors, are seen in animal populations: monogamous (monogamy), polygynous (polygyny), and polyandrous (polyandry).

Detailed explanation-2: -Mating behaviour in animals includes the signaling of intent to mate, the attraction of mates, courtship, copulation, postcopulatory behaviours that protect a male’s paternity, and parental behaviour.
