Explain with an example, how genes control the characteristics (or traits).
The gene is the section or part of DNA that carries information for a protein. This information is translated to synthesize protein (enzymes, hormones or proteins).
Therefore, each trait is the result of the biochemical reaction of this expressed form of a gene (protein).
The trait expressed by the dominant gene is known as a dominant trait.
The trait expressed by a recessive gene is a recessive trait.
For example, When the Pure tall pea plant (TT) is crossed with the dwarf (tt) pea plant, the trait expressed will be Tt, which will produce a tall pea plant. When this gene is passed from parent to offspring, the traits preserved upon them also passes with it.
