Phenotype
the Phenotype is the direct result of the genotype and the environment...... genotype + environment = Phenotype
A trait is a specific characteristic of an organism. Traits can be determined by genes or the environment, or more commonly by interactions between them. The genetic contribution to a trait is called the genotype. The outward expression of the genotype is called the phenotype.

Genotype
The genotype against the immediate environment and developmental processes. Each organism has a unique environment too. Think about it. Even identical twins are not totally their genotype because they are subject to not only the same environment, usually, but the unique experiences and formative processes of their unique environment.
The expression of a specific trait in an individual (such as hair color) is determined by two factors,one from each parent. These factors are represented with an uppercase letter for a dominantfactor and a lowercase letter for a recessive factor. The combination of these factors determineshow that trait will be expressed in an individual.
