Do Proteins Determine Phenotype?

Proteins Dictate Phenotype
Genotype controls phenotype because genes direct the production of proteins . Proteins, in turn, dictate virtually every reaction in the cell and thus are directly responsible for observable characteristics.

How is phenotype determined?

An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes. ... Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

What is the relationship between phenotypes and proteins?

The genotype—i.e., the genetic makeup of cells—and the phenotype have been in the limelight for decades. The genotype and phenotype have been linked through expression of the specific encoded proteins. The linkage has been understood in terms of the specific three-dimensional structures that they obtain.
