Phenotype,: characteristics of an organism result from the interaction with the environment

Genotype and phenotype are terms that are used to differentiate between the genetic makeup of an individual and which genes are to be expressed respectively.

Genotype is the complete gene set of an organism. Phenotypes are caused by the interactions of the many different proteins created by DNA. This process can get incredibly complicated. Even in the lowest lifeforms there are thousands of genes, creating thousands of different proteins. When some of these genes are expressed depending on the environmental conditions, characteristic features of that particular organism can be observed. These observable characters are referred to as the phenotype. The part of the phenotypes that is not visible can be observed in biochemical assays.

The phenotype of each individual is usually considered as an interaction between two variables: the genes each individual carries and the environment that they experience. The word ‘environment’ refers to general external factors that are (or could) be shared by groups of individuals, such as diet, exposure to pathogens and lifestyle.

The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging.

In natural evolving systems, phenotypes are organized into mutationally connected networks of genotypes, which increase the likelihood for an evolving population to encounter novel adaptive phenotypes (i.e., its evolvability).
