Monogamy: One male and one female have an exclusive mating relationship. The term "pair bonding" often implies this. This is associated with one-male, one-female group compositions. There are two types of monogamy: type 1, which is facultative, and type 2, which is obligate. Facultative monogamy occurs when there are very low densities in a ...
Polygyny threshold model graph. The polygyny threshold model is an evolutionary explanation of polygyny, the mating of one male of a species with more than one female. The model shows how females may gain a higher level of biological fitness by mating with a male who already has a mate. The female makes this choice despite other surrounding ...
A criticism against polygyny is that in almost all cultures and religious communities that practice it, polygyny is the only form of polygamy that is allowed; and, as such, this violates modern principles of equality between men and women, especially as in many such places females having multiple partners is violently punished through honor ...
The polygyny threshold model also shows the effects of female reproductive success when multiple females in the same territory mate with one male. In this situation, the female has the option of breeding with an unmated male in a poor-quality territory or with an already-mated male in a high-quality territory.
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 (/ ˈ p ɒ l i ˌ æ n d r i, ˌ p ɒ l i ˈ æ n-/; from Ancient Greek πολύ (polú) ' many ' and ἀνήρ (anḗr) ' man ') is a form of polygamy in which a woman takes two or more husbands at the same time.
In animal behavior, resource defense polygyny is a mating strategy where a male is able to support multiple female mates by competing with other males for access to a resource. [1] [2] In such a system, males are territorial. Because male movement is restricted, female-female competition for a male also results.
Technically, polygyny in sociobiology and zoology is defined as a system in which a male has a relationship with more than one female, but the females are predominantly bonded to a single male. Should the active male be driven out, killed, or otherwise removed from the group, in a number of species the new male will ensure that breeding ...
