Amplification is a judged tendency of a person to amplify physical symptoms based on negative psychological factors such as anxiety or depression.A distinct interpretation of amplification could be sensory processing disorder involving differences in the way a person reacts to sensory input, a symptom associated autism spectrum disorder.

The values given to different traits among human variability are often influenced by what phenotypes are more prevalent locally. Local valuation may affect social standing, reproductive opportunities, or even survival. Differences may vary or be distributed in various ways.
The effect of selection is to promote certain alleles, traits, and individuals that have a higher chance to survive and reproduce in their specific environment. Since the environment has a carrying capacity , nature acts on this mode of selection on individuals to let only the most fit offspring survive and reproduce to their full potential.
A peacock displays his long, colored tail, an example of secondary sex characteristics. An adult human's Adam's apple, a visible secondary sex characteristic common in males. A secondary sex characteristic is a physical characteristic of an organism that is related to or derived from its sex, but not directly part of its reproductive system. [1]
Whale reproduction follows a K-selection strategy, with few offspring, long gestation, long parental care, and a long period until sexual maturity. In ecology , r / K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring.

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.
Essentially, natural selection is a mechanism that contributes to directional gene selection in individuals that reproduce. Traits that cause greater reproductive success of an organism are favored, whereas those that reduce reproductive success are selected against. [17] [18] In contrast to learning, natural selection is solely a biological ...
