Mechanism for Expression of Traits
Mechanism of Expression of Traits:
A gene contains the information for making proteins in the cell. The proteins synthesized according to this information may be enzymes that catalyse biochemical reactions. Each trait is the outcome of several such biochemical reactions, each of which is controlled by a specific enzyme. If the enzyme is not produced because its gene is absent, that particular reaction will not occur and the trait resulting from its reaction will not appear phenotypically. Thus, each trait is controlled by a gene.
