Polygyny is more widespread in Africa than in any other continent. [2] Some scholars theorize that the slave trade's impact on the male-to-female sex ratio was a key factor in the emergence and fortification of polygynous practices in regions of Africa.
Polygynandry is another way to describe a multi-male and multi-female polygamous mating system. When females have multiple mating partners, it is known as polyandry , and when males have multiple mating partners, it is known as polygyny .
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 male.
Polygyny is more widespread in Africa than on any other continent, [31] [32] especially in West Africa, and some scholars see the slave trade's impact on the male-to-female sex ratio as a key factor in the emergence and fortification of polygynous practices in regions of Africa. [33]
Polygyny (the most common polygamous mating system in vertebrates so far studied): One male has an exclusive relationship with two or more females. This is associated with one-male, multi-female group compositions. Many perennial Vespula squamosa (southern yellowjacket) colonies are polygynous. [3]
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] A common example of polyandrous mating can be found in the field cricket ( Gryllus bimaculatus ) of the invertebrate order Orthoptera (containing crickets, grasshoppers, and ...
Both male and female reindeer grow antlers. This is a trait that no other species in the deer family possesses. The reason, a peculiar result of circumstances and biological luck, reflects.
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 ...
