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
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 ...
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]
The Coolidge effect is a biological phenomenon seen in animals, whereby males exhibit renewed sexual interest whenever a new female of reproductive availability is introduced, even after sex with prior but still available sexual partners.
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]
In a study done on great reed warblers, models based on the polygyny threshold and sexy-son hypotheses predict that females should gain evolutionary advantage in either short-term or long-term in this mating system. Although the importance of female choice was demonstrated, the study did not support the hypotheses. [33]
The Huffington Post and YouGov asked 124 women why they choose to be childfree. Their motivations ranged from preferring their current lifestyles (64 percent) to prioritizing their careers (9 percent) — a.k.a. fairly universal things that have motivated men not to have children for centuries.
Female assessment of the males (see Female Mate Choice) plays a role in the number of males opting to use an alternative mating technique. [6] Females are likely to not choose to mate with males of a lower quality, so these males will have to adopt alternative mating techniques in order to mate.
