Convenience Polyandry Hypothesis is the assumption that there is a greater cost for females when, refusing male mating attempts than in choice mating. [22] It is the situation in which females adjust their mating rate to balance the costs of male harassment.
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. Polyandry is contrasted with polygyny, involving one male and two or more females.
Overall, polyandry is the dominant mating system in lemon sharks [16] and sandbar sharks. [2] However, geography can play a role in mating systems. [16] For example, western north Atlantic sandbar sharks exhibit polyandry as the dominant mating system whereas in the Central Pacific, sandbar sharks do not have a dominant polyandry mating system ...
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. ... Genetic polyandry is found ...
Animal sexual behaviour and mate choice directly affect social structure and relationships in many different mating systems, whether monogamous, polygamous, polyandrous, or polygynous. Though males and females in a given population typically employ a predominant reproductive strategy based on the overarching mating system, individuals of the ...
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]
Polyandry occurs when one female gets exclusive mating rights with multiple males. In some species, such as redlip blennies , both polygyny and polyandry are observed. [ 26 ]
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 few males.
