center Genotype and Phenotype


The relationship between the genotype and phenotype is a simple one ...
The Genotype codes for the Phenotype

The "internally coded, inheritable information", or Genotype, carried by all living organisms, holds the critical instructions that are used and interpreted by the cellular machinary of the cells to produce the "outward, physical manifestation", or Phenotype of the organism.

Thus, all the physical parts, the molecules, macromolecules, cells and other structures, are built and maintained by cells following the instructions give by the genotype. As these physical structures begin to act and interact with one another they can produce larger and more complex phenomena such as metabolism, energy utilization, tissues, organs, reflexes and behaviors; anything that is part of the observable structure, function or behavior of a living organism.
