the dominant allele
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.
two or more genes
A piece of DNA which controls a trait is a gene variations of a gene are called alleles. If you mean "controls how much a particular trait is expressed" then you would be dealiung with the promoter region of a gene which is near the start and controls how strongly a gene is expressed.
The principle of excessiveness is defined as the explanation of why one trait will not show over another. If a trait is recessive it will not show when a dominant trait is present.
no, Deoxyribonucleic acid, DNA controls traits
a trait based on appearance, i believe.

The visible or detectable trait is known as the phenotype.

Paranoia is a mental state defined by extreme distrust and suspicion of others. It is considered a symptom of certain mental health conditions like paranoid personality disorder rather than a character trait.

Mendel identified the trait of dominance in certain genes.

recessive
polygenic inheritance
