Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.

You can show the precense og a trait with dark outline in a gene.

A recessive trait is one that will only be expressed when in the presence of two recessive alleles.

The expression of a specific trait in an individual (such as hair color) is determined by two factors,one from each parent. These factors are represented with an uppercase letter for a dominantfactor and a lowercase letter for a recessive factor. The combination of these factors determineshow that trait will be expressed in an individual.
It is what the trait does that you can see. Such as hair color and eye color
