Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.

There are basically two factors that influence the phenotype:

(1) Genotype or Genetic information of the individual: Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.

(2) Environmental influence: As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.

Hence, Genotype and environmental factors influence an individuals phenotype.
