In polygynous systems there is less genetic diversity due to the fact that one male sires all of the offspring. , From an evolutionary standpoint, the most predominant characteristic that is often found in polygynous mating systems is extreme sexual dimorphism. (1989). In the end, everyone should decide for themselves whether a polygamous lifestyle is suitable for them or if they rather want to spend their lives with only one partner instead. Most such species exhibit polygyny, in which males have multiple partners. Premium Membership is now 50% off! Polygamy means a marriage between multiple people, whereas in a monogamy a person … , When two animals mate, they both share an interest in the success of the offspring, though often to different extremes. , Strongly polygynous or monogamous species display increased female–female aggression. Extra-pair copulations exemplify sexual conflict, a situation in which one behavior is advantageous for one sex, but disadvantageous for the other.. , Extra-pair copulations are a strategy used by females to avoid the sexual conflict caused by polygyny, allowing them access to better mate choice.  Because females do not need extra help raising their nests, males can afford to invest in multiple females. PREVIOUS ARTICLE The Pros and Cons of Zoos May 15, 2015 - 6:52 pm. Monogamy does not exclude 'genetic promiscuity', i.e., extra-pair mating. Aggressive competition between males, female-controlled polygyny and sexual monomorphism in a Malagasy primate, https://en.wikipedia.org/w/index.php?title=Polygyny_in_animals&oldid=977024794, Articles with unsourced statements from March 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 September 2020, at 13:48. For example, female great reed warblers (Acrocephalus arundinaceus) have a preference to mate with males with larger song repertoires, because this indicates that they are older and may have better nesting territories. In a mating system, the limiting sex (usually females) is the one that the limited sex (usually males) tries to monopolize. Instead, it is much more common for polygynous mating to happen. …social monogamy is common and polygamy rare in birds, the converse is true in mammals; a large fraction of mammals are polygamous. It’s very easy for women to fall into a trap of dependence and objectification as a possession. Polygamy has got several disadvantages as compared to its advantages and for this reason; there are some countries where the government has illegalized the issue of polygamy. Females in the harem are able to breed at the same time, indicating that harem size and the number of male offspring are related. Davies, N. B., Krebs, J. R., & West, S. A. ADVERTISEMENTS: (2) Jealousy, hatred and quarrel among the women are found due to lack of understanding among the wives. Following are the disadvantages of polygyny: (1) The status of women suffers in a society of polygyny. Interviews with the Code Talkers. A MARRIAGE OF EQUALS: The consequences of monogamy on economic and social development in Europe One of the fundamental institutions that determine family systems and female agency in a country is monogamy versus polygamy. Monogamy can exist with or without marriage, and can be practiced by people of all sexual orientations. A wide-ranging song repertoire develops with age, and older males are more likely to dominate better territories, giving a plausible reason as to why females prefer older males. Unlike in males, extra-pair copulations are advantageous for females because they present females with more mate choice as well as increase the genetic diversity of the community. The largest advantage for males in a polygynous mating system is the increased fitness and reproductive success of the lone male because he will father all the offspring. , It is also possible that broad song repertoires are a supplementary cue for a good mate, in conjunction with male territory size and quality. Often, females will fight for resources from the male, such as food and nest protection. The other disadvantage of polygamy is that it will lead to conflicts and misunderstandings. ) These breeding males also have short tenure, and it is common for groups of males who do not have harems to attack a breeding male in order to gain reproductive access to his females.
