Which of the following is incorrect?

#Section 4: Behavioural Ecology
  1. In promiscuous mating systems, each male or female may mate with multiple partners more commonly in Chimpanzees and bonobos

  2. Monogamy, each individual mates exclusively with one partner over at least one breeding season and sometimes for longer and commonly observed in birds, some rodents, and a few primate species.

  3. In polygyny, one male mates with more than one female in a single breeding season, but females mate only with one male and associated with uniparental care of young, with males contributing little.

  4. In polyandrous species, sexual dimorphism is absent, both of the sexes generally similar in size
