Polygyny (/ p ə ˈ l ɪ dʒ ɪ n i /; from Neo-Greek πολυγυνία, from πολύ-(polú-) 'many' and γυνή (gunḗ) 'woman, wife') [1] is a mating system in which one male lives and mates with multiple females but each female only mates with a single male.
Polygynandry is a mating system in which both males and females have multiple mating partners during a breeding season. [1] In sexually reproducing diploid animals, different mating strategies are employed by males and females, because the cost of gamete production is lower for males than it is for females. [2]
Polygyny is where one male mates with several females in a breeding season (e.g., lions, deer, some primates, and many systems where there is an alpha male). [1] A common example of polyandrous mating can be found in the field cricket ( Gryllus bimaculatus ) of the invertebrate order Orthoptera (containing crickets, grasshoppers, and ...
Polygyny is associated with an increased sharing of subsistence provided by women. This is consistent with the theory that if women raise the children alone, men can concentrate on the mating effort. Polygyny is also associated with greater environmental variability in the form of variability of rainfall. This may increase the differences in ...
A study on the association of alpha males and females during the non-breeding season in wild Capuchin monkeys examined whether alpha males are the preferred mate for females and, secondly, whether female-alpha status and relationship to the alpha-male can be explained through the individual characteristics and or social network of the female.

Females are larger in many species of insects, many spiders, many fish, many reptiles, owls, birds of prey and certain mammals such as the spotted hyena, and baleen whales such as blue whale. As an example, in some species, females are sedentary, and so males must search for them.
Some other examples include lung diseases such as pneumonia, metabolic disorders such as hypocalcemia, kidney diseases like renal cell carcinoma, and hiccups can also be a symptom of tumors in the ...
Polyandry in fishes is a mating system where females mate with multiple males within one mating season. [1] This type of mating exists in a variety of animal species. [1] Polyandry has been found in both oviparous and viviparous bony fishes and sharks. [2]
