A single gene trait is a specific characteristic or phenotype that is influenced by the expression of a single gene. This means that the presence or absence of a particular trait is determined by variations in one specific gene. Examples include earlobe attachment, hair color, and tongue rolling.

A single gene can influence multiple traits A single trait can be controlled by multiple genes
The trait for fur color can be both. In some species, like mice, fur color is determined by a single gene with different alleles. In other species, like dogs or humans, fur color can be controlled by multiple genes interacting together (polygenic trait).
A single-gene trait is a phenotypic trait controlled by two homologous alleles.

A polyallelic trait is a trait controlled by multiple alleles (variants of a gene) at a single gene locus. This means there are more than two possible alleles that can influence the trait's expression, resulting in a range of phenotypic variations. This can lead to a complex inheritance pattern.

A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.

The trait for fur color can be both. In some species, like mice, fur color is determined by a single gene with different alleles. In other species, like dogs or humans, fur color can be controlled by multiple genes interacting together (polygenic trait).
An example of a gene with three or more alleles for a single trait is the ABO blood group gene. This gene has three main alleles - A, B, and O - which determine blood type. The different combinations of these alleles result in the various blood types (A, B, AB, and O) observed in humans.
