 Female resistance traditionally includes reducing negative effects to mechanisms implemented by males, but outside the norm may include sexual cannibalism, increased fitness in females on offspring and increased aggression to males.Animal species that are not in a state of sexual conflict are more likely to be in sync to the male dominance hierarchy as the females are more docile in these organizations such as wolves, common rabbits and crocodiles.Others, such as spiders, ants and orcas are female-dominated.
