multiple allelic series
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.
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.
multiple alleles
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
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.
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.
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.
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.
Multiple alleles is when there are more than 2 alleles in a single trait. In blood type, instead of either one dominant and one recessive type alleles, there is one recessive allele (type O) but two dominant alleles(type A and B). Polygenic inheritance is when more than one gene controls a single trait, such as height in which three genes are responsible.
multiple alleles
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.)
When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance. Many quantitative characters have polygenic inheritance. Inheritance of blood groups is an example of polygenic inheritance in human being.When more than two alleles are involved in the inheritance of a trait, it is called polygenic inheritance.

They are both controlled by more than 2 alleles
polygenic inheritance :)
three or more, or multiple
Alleles are alternative forms of genes.
I think that , they r both controlled by more then 2 allels.
