Unless an organism has more than two copies of at least one chromosome, or more than two copies of their entire genome (known as polyploidy), they will only have, at most, two alleles of any one gene. Haploid organisms only have -one-. The only other way to get two copies of a gene into an organism is through splicing.
If, however, you're asking if -any- gene has more than two alleles, across all organisms that share said gene, yes. In fact, a very significant portion of known genes do.
Most of the time, these are just minor mutations, but sometimes they may serve entirely different functions, or may not function at all.

What is multiple alilism?
The genes which have more than one alleles are called multiple allelic genes and this phenomenon is known as multiple allelism.
In what are there more than two possible alleles for a trait?
gene therapy/ Polygenic trait
What is the difference between alleles and 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.
Are alleles more than genes or genes more than alleles in eukaryotic cells?
An allele is essentially the same as a gene so there is no difference in quantity between the two in any cell. Gene is a more common general reference to genetic material at a particular locus whereas allele often refers to an example of variation at a gene locus. For example the allele for tall (T)
Traits produced by two or more genes are codominant?
yes but the mans genes are shown more in the child is that your question cause i might be totaly wrong. ---- Genes from each parent show equally and codominant alleles produces a interleaved pattern rather than a blended pattern like incomplete dominance genes.
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.
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 genes that have more than two alleles?
ABO blood groups in humans,Coat color in rabbits is determined by four alleles,human-leukocyte-associatedantigen(HLA) genes
What is multiple alilism?
The genes which have more than one alleles are called multiple allelic genes and this phenomenon is known as multiple allelism.
In ------ these are more than two alleles possible for a trait?
polygenic inheritance :)
Two ways multiple alleles and polygenic traits differ?
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.
More than one pair of alleles controls a trait?
It isn't genome the definition of genome is a map of the location of individual genes on every chromosome of an individual. It's multiple alleles- having more than two alleles that control a trait. PS- I got this information from my text book:)

Tell you about polygenic inheritance under genetics?
Multiple alleles are the presence of more than two alleles for a trait within a gene pool, while polygenetic traits are controlled by multiple genes.

Why do scientists need to trace triats from one generation to the next?
To get a working mathematical model of how genes and interactions between them work, in what conditions and interactions with other genes they manifest and when they do not. It's also possible to get a mathematical model of recessive and dominant genes as well based on a genealogy. or codominance, accumulated inheritance with more than one pair of alleles, etc.
