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 ]
The precise meaning depends upon the context. With respect to animals , the term describes which males and females mate under which circumstances. Recognised systems include monogamy , polygamy (which includes polygyny , polyandry , and polygynandry ), and promiscuity , all of which lead to different mate choice outcomes and thus these systems ...
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.
Some taxa with high social organization are eusocial, meaning that a single female (e.g., the queen bee) or caste produces offspring while the other organisms (e.g., non-reproductive female worker bees) cooperate in caring for the young.

Polygynandry also exists, in which two males jointly defend a territory containing several females. Polyandry, though, is the most common mating system of dunnocks found in nature. Polyandry, though, is the most common mating system of dunnocks found in nature.
Flu A and flu B are the most common strains of the flu that circulate in humans. The U.S. is currently in the middle of flu season, with a high number of cases reported across the country.
Cooperative breeding encompasses a wide variety of group structures, from a breeding pair with helpers that are offspring from a previous season, [2] to groups with multiple breeding males and females (polygynandry) and helpers that are the adult offspring of some but not all of the breeders in the group, [3] to groups in which helpers ...
