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.
The blood type trait that is controlled by more than two alleles for a given gene is known as the ABO blood group system. It involves three alleles: A, B, and O, which determine blood types A, B, AB, and O. This system results in four possible blood types due to the combination of these multiple alleles.
Alleles refer to different versions of the same gene. So a single gene can have multiple alleles. For example in fruit flies there is a single gene that controls eye color, and the eye color of the fly depends on the alleles they have for that gene (since they have two copies of every gene, being diploid). A polygenic trait refers to any inheritable trait that is controlled by multiple genes, and each of these genes can have multiple alleles. For example, eye color in humans is a polygenic trait. There are at least three different genes, each with multiple alleles, that determine eye color in humans. Polygenic traits don't follow patterns of mendelian inheritance. So in summation the difference is multiple alleles refers to different versions of one gene and polygenic traits refers to a single trait which is controlled by multiple genes (each with multiple alleles) Yes, or: Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
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.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
The ABO blood groups in humans are controlled by multiple alleles.
A single-gene trait is a phenotypic trait controlled by two homologous alleles.

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.
A single gene can influence multiple traits A single trait can be controlled by multiple genes
This phenomenon is known as multiple allelism, where there are more than two different variations of a gene (alleles) that can affect a single trait. In this case, individuals can inherit one of several possible alleles for the trait. Examples include the ABO blood group system in humans, where there are three alleles (IA, IB, i) that determine a person's blood type.
Traits controlled by a gene with multiple alleles can vary in terms of expression or phenotype. For example, human blood type (A, B, AB, O) is controlled by a gene with multiple alleles. The different alleles can result in different phenotypes (A, B, AB, O) for the same trait.
E. Multiple alleles. Multiple alleles refers to a gene that has more than two alleles which can result in a larger number of possible trait variations. This is different from traits that are controlled by dominant and recessive alleles, or exhibit incomplete dominance.
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes.
