Adaptive value

The adaptive value represents the combined influence of all characters which affect the fitness of an individual or population.

This heritable trait that can help offspring to cope with the new surrounding or condition is a measurable quantity.

[2] 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.

[3] The adaptive value can be measured by contribution of an individual to the gene pool of their offspring.

The adaptive values are approximately calculated from the rates of change in frequency and mutation–selection balance.
