| GENOTYPE |
The genotype of the organism is the actual genetic material--the DNA and the genes for which it codes.
This is determined through the processes of meiosis and fertilization.
In "translating" from genotype to phenotype--which is what protein does--significant epigenetic (gene "control" mechanisms) and environmental factors effect the manifestation of traits. In addition, the physiologic expression is subject to "penetrance" and "expressivity" factors that are unique to the genes themselves.
The phenotype of the organism includes the traits that the organism DISPLAYS--color, shape, size, etc. This would include "abnormal" gene expressions, i.e. diseases.
