Give scientific reasons for the following statements:
The characters are under the control of genes.

Explanation

A gene is the unit of heredity. It is a segment of DNA of specific length, arranged sequentially along the length of the chromosome. Each gene is functionally specific and synthesizes a specific type of protein. The enzymes are all proteins and these proteins (as enzymes) for the species because adaptation causes survival of species induce specific biochemical process. The substances or proteins, formed during these processes, are responsible for the expression of characters. Hence, the characters are under the control of genes.
