A single-gene trait is a phenotypic trait controlled by two homologous alleles.
A single gene can influence multiple traits A single trait can be controlled by multiple genes
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 non Mendelian trait can be controlled by one gene. When a trait is controlled by one gene it results in genetic disorders. Examples of disorders due to single gene inheritance - Huntington disease, Fragile-X syndrome.
A trait controlled by many genes
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
Its possible. A single gene defines a single protein.
One example of a trait controlled by a single gene with two alleles is flower color in snapdragons. The gene responsible for flower color has two alleles: one for red flowers and one for white flowers.
No, the frizzle trait in chickens is not an example of pleiotropy. Pleiotropy refers to a single gene affecting multiple traits. However, the frizzle trait is controlled by a single gene that affects only one observable trait - the curliness of feathers.

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.
