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 ...
Not all socially monogamous species exhibit pair bonding, but all pair bonding animals practice social monogamy. These characteristics aid in identifying a species as being socially monogamous. At the biological level, social monogamy affects the neurobiology of the organism through hormone pathways such as vasopressin and oxytocin. [13]
The following are some of the mating systems generally recognized in animals: 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 ...
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]
Male (left) and female (right) mallard ducks form seasonal monogamous pairs. In various species, males provide parental care and females mate with multiple males. For example, recent studies show that extra-pair copulation frequently occurs in monogamous birds in which a "social" father provides intensive care for its "social" offspring. [5]
Gorilla Great reed warbler. When two animals mate, they both share an interest in the success of the offspring, though often to different extremes. Unless the male and female are perfectly monogamous, meaning that they mate for life and take no other partners, even after the original mate's death, the amount of parental care will vary. [7]
“Monogamous people may have a similar bias because they might worry that an ambiamorous person will be interested in non-monogamy again at some point in their lives,” she explains.
Gibbons, on the other hand, are an example of monogamous primates that can be described as “monomorphic,” meaning males and females appear the same with little to no sexual dimorphism. [2] The correlation between mating system and dimorphism in haplorhines likely indicates sexual selection is the driving force behind dimorphism in species ...
