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.
When more than two different alleles control a trait?
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.
What is the condition whereby a trait is determined by three or more alleles called?
The condition whereby a trait is determined by three or more alleles is called multiple allelism. Multiple alleles refer to the presence of more than two alleles of a gene within a population. This can result in various combinations of traits and phenotypes.
Two ways multiple alleles and polygenic traits differ?
Multiple alleles involve more than two alternative versions of a gene, while polygenic traits are controlled by the interaction of multiple genes. Multiple alleles can have more than two alleles, whereas polygenic traits involve the additive effects of multiple genes on a single trait.
How are multiple alleles different from polygenic traits?
Multiple alleles refer to three or more alternative forms of a gene that can exist within a population, while polygenic traits are controlled by multiple genes, each with different alleles contributing to the phenotype. Multiple alleles involve variations of a single gene, while polygenic traits involve multiple genes interacting to determine a trait.
When a gene has more than two alleles the condition is known as?

What is multiple aleles?
Multiple alleles indicates that either the study is being conducted on alleles at more than one gene locus, that the characteristic being studied is controlled by several alleles at different loci or that there are two or more alleles at a single gene locus.
How many alleles for a trait are contained in the offsrping?
Depends on the gene. Can be as few as 2, or more than that. Height, hair colour etc have multiple alleles.

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.

A population of an organism sHow is more than two alleles for a characteristic this is a case of?
This is a case of multiple allelism. Multiple allelism refers to the presence of more than two alleles for a particular gene in a population. Each individual will still only have two of these alleles.
What are multiple allels in biology?
Multiple alleles is a type of heredity in which one gene has more than two alleles. For example, in humans the gene for blood group has three alleles, A, B, and O. Even though there are three alleles in the population, a person can only inherit two alleles, one from his/her mother and one from his/her father.
Two ways multiple alleles and polygenic traits differ?
Multiple alleles involve more than two alternative versions of a gene, while polygenic traits are controlled by the interaction of multiple genes. Multiple alleles can have more than two alleles, whereas polygenic traits involve the additive effects of multiple genes on a single trait.
What is multiple allele gene expression?
Multiple allele gene expression refers to a situation where a single gene has more than two alleles, or different versions of the gene, which can be expressed differently within an individual's genotype. This can lead to a wider range of possible phenotypic outcomes because each allele may contribute to the expression of a specific trait.
How are multiple alleles different from polygenic traits?
Multiple alleles refer to three or more alternative forms of a gene that can exist within a population, while polygenic traits are controlled by multiple genes, each with different alleles contributing to the phenotype. Multiple alleles involve variations of a single gene, while polygenic traits involve multiple genes interacting to determine a trait.
