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 ...
Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another. [1] As an example, in the cichlid species Variabilichromis moorii , a monogamous pair will care for eggs and young together, but the eggs may not all be fertilized by the ...
Infanticide is observed to be the major cause of mortality in various mammals. Polyandry is thought to evolve from their offspring's vulnerability to infanticide. [31] There is evidence that polyandry is an effective strategy that is adapted by many to increase their offspring survival through the avoidance of male infanticide.
Polyandry is a mating system by which a female mates with more than one male; the male, in turn, can also mate with more than one female. In a monogamous setting, both male and female consent to having only one mate at any one time and thus mate only with that partner for that time period.
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 sociobiology and zoology, researchers use polygamy in a broad sense to mean any form of multiple mating. In contrast to polygamy, monogamy is marriage consisting of only two parties. Like "monogamy", the term "polygamy" is often used in a de facto sense, applied regardless of whether a state recognizes the relationship.
Monogamy (/ m ə ˈ n ɒ ɡ ə m i / mə-NOG-ə-mee) is a relationship of two individuals in which they form a mutual and exclusive intimate partnership.Having only one partner at any one time, whether that be for life or whether that be serial monogamy, contrasts with various forms of non-monogamy (e.g., polygamy or polyamory). [1]
In humans, social monogamy takes the form of monogamous marriage. Sexual monogamy is defined as an exclusive sexual relationship between a female and a male based on observations of sexual interactions. Finally, the term genetic monogamy is used when DNA analyses can confirm that a female-male pair reproduce exclusively with each other.
