The "Hidden Survival Muscle" In Your Body



andry. For example, in the bee species Anthidium maculosum, like in many other species, the high cost of resisting mating may exceed the cost of accepting numerous males in a breeding if copulating takes a short time, and therefore females in some species are inclined to being polyandrous. In the polyandrous system, sexual coercion has been observed to be one of the major reasons for why females begin to mate with multiple males to outweigh the cost under different circumstances. The sexual conflict hypothesis suggest that polyandry can occur due to sexual coercion preventing females from obtaining any benefits. Sexual coercion has been seen in three different forms: forced copulation, sexual harassment, and intimidation. Forced copulation is seen in those males that cannot gain access to females for mating. As a result of the lack of access to mates, males are more likely to engage in sexually aggressive behaviors that could result in physical harm and death for females, as has been
  observed in elephant seals and ducks. Intimidation was seen in social primates, who coerce females into mating, therefore, pushing them to mate with their own aggressor. Males use intimidation as a method of punishment in females that do not mate with them.

Sexual coercion has many benefits to males allowing them to mate, but their strategies pose high cost for females. This has been observed in vertebrates like green turtles. The green turtles is an example of a species that does not receive any possible benefit from polyandry and only uses it to reduce the cost of mating. As for house mice, multiple male mating was observed even when females had the opportunity to select their mate without sexual coercion, showing that it was due to female choice. In the fly Dryomyza anilis, females favor matings with quick oviposition. D. anilis females can store sperm for at least two egg batches without their fertilization rate decreasing. Therefore, mating before each oviposition is not necessary. There is no significant overall benefit for females in multiple matin
