The genotype describes the genes inherited by an organism. Phenotype refers to an individual's anatomical structure, physiology and behavior. The phenotype refers to everything that can be easily observed and measured about a plant, animal or human being.

Our phenotype is the product of Genes inherited from our biological parents, Our environment And developmental noise Phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). In a narrow "genetic" sense, the genotype defines the phenotype. But how, in and evolutionary sense, does the phenotype "determine" the genotype? Selection acts on phenotypes because differential reproduction and survivorship depend on phenotype.

If the phenotype affecting reproduction or survivorship is genetically based, then selection can winnow out genotypes indirectly by winnowing out phenotypes.(Anderson, R.W.) Distinguish between phenotype and genotype. Living material is unique in that its composition and form is represented in two radically different formats, called phenotype and genotype. The physical material itself - an arm, cell, and chunk of meat or thymus gland - constitutes its phenotype.

It is more than what is visible by eye or microscope however, as it includes the full complement of behaviors, the developmental dynamics, as well as the chemical composition of the organism. Genetic representations are inscribed in a code in DNA molecules infused throughout all biological tissues. Every cell contains a complete genetic description of not only its own phenotype but of the whole organism encompassing it. A fat cell in the belly contains the complete genetic information for brain neurons as well as itself.

Every speck of tissue visible to the eye carries hundreds or thousands of these genetic representations in the chromosomes of its cells. Moreover, they do not merely describe but are part of an elaborate cellular machinery to cause a body part to develop the form of those descriptions. The genotype is the full complement of the genetic information repeated exactly in every body cell.

It is a major determinant of the phenotypic attributes of the organism, which is why an egg laid by a hen hatches as a chick instead of a duckling. But, genes are not exclusively responsible for a person's phenotype. In general phenotypic traits are specified or "determined" by a combination of genetic and environmental factors. The way genes interact with the environment is complex. One popular conceptualization is that the genotype specifies potential for a person's traits or abilities and the environment determines how fully that potential is reached.

Another view is that genes and the environment have additive.
