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.
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.
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.
What is it called when there are more than two alleles present in a population?
Chromosomes are made of tightly wound DNA and protein. Genes are found along the length of chromosomes. A gene is a segment of DNA that contains instructions for making a specific protein or proteins required by the body. Human beings have about 30,000 - 35,000 genes. We have two copies of each gene, but the copies can be slightly different. For example, the gene associated with cystic fibrosis has more than 1000 different variations. Different versions of the same gene are called its alleles, and everyone has two alleles for each gene. (Males have only one X chromosome, so they only have one copy of the genes located on the X chromosome.)
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.
When a gene has more than two alleles the condition is known as?
multiple alleles

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.
The blood type trait which is controlled by more than two alleles for a given gene and therefore is called?
multiple alleles
What is multiple allele gene expression?
Instead of having only two alleles for a trait, there are more than two. An example in humans is the ABO blood group system, where there are three alleles that are possible. However, an individual can only inherit the alleles of his/her parents, for a total of two alleles.
An inheritance pattern in which a gene has more than two alleles?
multiple allelic series
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.
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.
