A study on the association of alpha males and females during the non-breeding season in wild Capuchin monkeys examined whether alpha males are the preferred mate for females and, secondly, whether female-alpha status and relationship to the alpha-male can be explained through the individual characteristics and or social network of the female.

Horses can breed with Przewalski's horse to produce fertile hybrids. Mule, a cross of female horse and a male donkey. Hinny, a cross between a female donkey and a male horse. Mules and hinnies are examples of reciprocal hybrids. Kunga, a cross between a donkey and a Syrian wild ass. Zebroids. Zeedonk or zonkey, a zebra/donkey cross. Zorse, a ...
Therefore, mating before each oviposition is not necessary. There is no significant overall benefit for females in multiple matings; large females are at an advantage due to their ability to resist unnecessary matings. [21] As a result of multiple male mating, multiple paternities were observed in species as a result of convenience polyandry. [4]

The second breeding female will receive fewer resources from the male than the first breeding female. However, if the bigamous threshold is higher than the second female's original resource threshold, the female will enter into a polygynous mating system, since she would still benefit from acquiring more resources.
One female plays the role played by the male in closely related species, and mounts the female that is about to lay eggs. This behaviour is due to the hormonal cycles of the females, which cause them to behave like males shortly after laying eggs, when levels of progesterone are high, and to take the female role in mating before laying eggs ...
A lower-cost alternative mating strategy, useful to bachelors without a harem, is kleptogyny (from Greek klepto-"stealing" and -gyny "female"), where a male sneaks in to mate while the harem owner is distracted: in the case of red deer, when the harem stag is involved in a fight with another older stag.
Foundation stock or foundation bloodstock refers to animals that are the progenitors, or foundation, of a breed or of a given bloodline within such. Many modern breeds can be traced to specific, named foundation animals, but a group of animals may be referred to collectively as foundation bloodstock when one distinct population (including both landrace breeds or a group of animals linked to a ...
