Phenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner. [1]
Phenotypic variation (due to underlying heritable genetic variation) is a fundamental prerequisite for evolution by natural selection. It is the living organism as a whole that contributes (or not) to the next generation, so natural selection affects the genetic structure of a population indirectly via the contribution of phenotypes.
A phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye color. Underlying genes, that make up the genotype, determine the hair color, but the hair color observed is the phenotype.

In sociology, a social system is the patterned network of relationships constituting a coherent whole that exist between individuals, groups, and institutions. [1] It is the formal structure of role and status that can form in a small, stable group. [1]
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
Visual sociology attempts to study visual images produced as part of culture. Art , photographs , film , video , fonts , advertisements , computer icons , landscape , architecture , machines , fashion , makeup , hair style , facial expressions , tattoos , and so on are parts of the complex visual communication system produced by members of ...
Phenotypic integration and its evolution can not only create large amounts of variety among phenotypes which can cause variation among species. For example, the color patterns on Garter snakes range widely and are caused by the covariance among multiple phenotypes. Phenotypic Integration is important for many traits.
