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.

What is a trait controlled by three or more alleles have?
multiple alleles
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
Difference between multiple alleles and multiple genes?
Alleles are different forms of the same gene. For example, if eye colour was coded for by just one gene, blue eyes would be one allele and green eyes would be another. Different genes, however, code for different things, so you might have a gene for eye colour and another for hair colour.
What are some human traits that are caused by multiple alleles?
The heredity of the ABO blood groups are governed by multiple alleles.
When more than two different alleles control a trait?
The presence of more than two alleles that control a trait is called multiple allele. An example of this is the group gene of ABO blood that has three alleles.
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What are the multiple forms of genes called?
Alleles are genes that exist in multiple forms.
What is a trait controlled by three or more alleles have?
multiple alleles
How do you know that human height is not multiple alleles?
It is based on multiple alleles.
What is the difference between a single gene and a polygenics trait?
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.
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
A trait controlled by four alleles is said to have?
A trait controlled by four alleles is said to have multiple alleles.
Difference between multiple alleles and multiple genes?
Alleles are different forms of the same gene. For example, if eye colour was coded for by just one gene, blue eyes would be one allele and green eyes would be another. Different genes, however, code for different things, so you might have a gene for eye colour and another for hair colour.
When a gene has more than two alleles the condition is known as?
multiple alleles
What are genes with three or more alleles called?
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
