Compare and Contrast Genotype & Phenotype

The Genotype is the genetic constitution of a cell, an organism, or an individual. For instance, the human albino gene has two allelic forms, dominant A and recessive a, and there are three possible genotypes- AA (homozygous dominant), Aa (heterozygous), and aa (homozygous recessive).

A Phenotype is any observable characteristic or trait of an organism; such as its morphology, development biochemical or physiological properties, or behavior. Phenotypes result from the expression of an organism's genes as well as the influence of environment factors and possible interactions between the two.

So Genotype is in the DNA and changes in the DNA. Phenotype is how the change looks like from outside. So what ever the result is from Genotype is seen by Phenotype. The mutation in the DNA or change in the Genotype necessarily doesn't show... while Phenotype is observable.
