Definition: Phenotype is defined as an organism's expressed physical traits. Phenotype is determined by an individual's genotype and expressed genes, random genetic variation, and environmental influences.Examples: Examples of an organism's phenotype include traits such as color, height, size, shape, and behavior.efinition: Phenotype is defined as an organism's expressed physical traits.

The Genotype is that part (DNA sequence) of the genetic makeup of a cell, and therefore of an organism or individual, which determines a specific characteristic (phenotype) of that cell/organism/individual.he distinction between genotype and phenotype is commonly experienced when studying family patterns for certain hereditary diseases or conditions, for example, haemophilia. Due to the diploidy of humans (and most animals), there are two alleles for any given gene.
