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.
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.
The two or more related genes that control a trait are known as?
alleles
Genes that have more than two possible alleles are said to have?
multiple alleles. These are alternative forms of a gene that can exist at the same locus on a chromosome. Each individual still carries only two alleles, but the population as a whole may have more than two different alleles for that gene.
What does a genes have two or more of?
Genes can have two or more alleles, which are different versions of a gene that can exist at a specific locus on a chromosome. These alleles can contribute to variations in traits among individuals. In diploid organisms, such as humans, genes typically have two alleles, one inherited from each parent. The combination of these alleles can determine the expression of specific traits.
What has same alleles?
Two or more genes which control the same characteristic.
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.
An inheritance pattern in which a gene has more than two alleles?
Polygenic inheritance is an inheritance pattern in which a trait is controlled by multiple genes, each with two or more alleles. This results in a continuous range of phenotypes rather than distinct categories.
What do genes that have more than two possible alleles have?
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 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.
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:)
What organisms with two alleles are called?
Genes
