The adaptive value represents the combined influence of all characters which affect the fitness of an individual or population.
Adaptive value is an essential concept of population genetics. It represents usefulness of a trait that can help an organism to survive in its environment. This heritable trait that can help offspring to cope with the new surrounding or condition is a measurable quantity. Measuring adaptive value increases our understanding of how a trait helps an individual's or population's chances of survival in a particular set of conditions.
The adaptive value can be measured by contribution of an individual to the gene pole of their offspring.The adaptive values are approximately calculated from the rates of change in frequency and mutation–selection balance.
- Avoiding Predators Some plants use indirect plant defenses to protect themselves against their herbivorous consumers. One of defensive mechanism that plants employ is to release volatile chemicals when herbivorous are feeding from them. The odor of volatile attracts carnivores’ attention, and they get rid of herbivorous by eating them.
- Sexual Reproduction Advantages Sexual mimicry is common among animals. Male cuttlefishes uses this strategy to gain advantage over other males competitor. They mimic female cuttlefish’s marking to fool guarding male and fertilize their females. This strategy has more success rate than normal courtship.
