Polyandry is often compared to the polygyny system based on the cost and benefits incurred by members of each sex. 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 ]
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 ...
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
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 ]
Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polygamy, [1] group or conjoint marriage. [2] In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage.
For instance, monogamy infers exclusive mating access and, thus, greater paternity certainty. Observed mating systems in primates include: monogamy, polyandry, polygyny and polygamy (as described below). Monogamy, or a monogamous mating system, is when one adult male and one adult female have a preferential partner for copulation. [1]
During the 2023 holiday season, which ran from Nov. 1, 2022, to Jan. 31, 2023, about 14,900 people were treated at hospitals for holiday decorating-related injuries, the CPSC said.

Animal sexual behaviour takes many different forms, including within the same species. Common mating or reproductively motivated systems include monogamy, polygyny, polyandry, polygamy and promiscuity.
