Sensory exploitation by males is one mechanism that involves males attempting to overcome female reluctance. Interlocus sexual conflict reflects interactions among mates to achieve their optimal fitness strategies and can be explained through evolutionary concepts. After this event, females' fitness depression decreases, and the cycle starts again. Following this event, females may develop a counter-adaptation, that is, a favorable trait that reduces the direct costs implemented by males. ![]() These favorable traits will cause a reduction in the fitness of females due to their persistence. The perpetual cycle begins with the traits that favor male reproductive competition, which eventually manifests into male persistence. Similarly, interlocus sexual conflict can be the result of what is called a perpetual cycle. Sexual conflict may lead to antagonistic co-evolution, in which one sex (usually male) evolves a favorable trait that is offset by a countering trait in the other sex. Evidence indicates that intralocus conflict may be an important constraint in the evolution of many traits. This conflict is resolved via elaborate sexual dimorphism thus maintaining sexually antagonistic alleles in the population. As a result, the alleles for such phenotypic traits exist under antagonistic selection. However, it also makes an individual more vulnerable to predators. Ornamentation could be costly to produce, but it is important in mate choice. An example would be the bill color in zebra finches. Intralocus sexual conflict – This kind of conflict represents a tug of war between natural selection on both sexes and sexual selection on one sex.Another well-documented example of inter-locus sexual conflict are the seminal fluid proteins of Drosophila melanogaster, which up-regulate females' egg-laying rate and reduces her desire to re-mate with another male (serving the male's interests), but also shorten the female's lifespan, reducing her fitness. Therefore, males have numerous adaptations to induce females to mate with them. Males frequently have a higher optimal mating rate than females because in most animal species, they invest fewer resources in offspring than their female counterparts. An example is conflict over mating rates. Interlocus sexual conflict is the interaction of a set of antagonistic alleles at one or more loci in males and females.There is some evidence for sexual conflict in plants. It has primarily been studied in animals, though it can in principle apply to any sexually reproducing organism, such as plants and fungi. According to chase-away selection, continuous sexual conflict creates an environment in which mating frequency and male secondary sexual trait development are somewhat in step with the female's degree of resistance. ![]() The development of an evolutionary arms race can also be seen in the chase-away sexual selection model, which places inter-sexual conflicts in the context of secondary sexual characteristic evolution, sensory exploitation, and female resistance. Sexual conflict underlies the evolutionary distinction between male and female. In one example, males may benefit from multiple matings, while multiple matings may harm or endanger females, due to the anatomical differences of that species. ![]() Sexual conflict or sexual antagonism occurs when the two sexes have conflicting optimal fitness strategies concerning reproduction, particularly over the mode and frequency of mating, potentially leading to an evolutionary arms race between males and females. Term in evolutionary biology Drosophila melanogaster (shown mating) is an important model organism in sexual conflict research.
