In what are there more than two possible alleles for a trait?
gene therapy/ Polygenic trait
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
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.
The blood type trait which is controlled by more than two alleles for a given gene and therefore is called?
multiple alleles
How many genes are needed to represent a trait?
It depends on the trait. Some traits exhibit simple Mendelian heredity, being governed by only one gene. However, many traits are governed by more than one gene, which is called polygenic inheritance.
What decides a trait?
When more than one gene influences that particular trait.
In what are there more than two possible alleles for a trait?
gene therapy/ Polygenic trait
Can a single gene control a single trait.?
It was once believed that one gene controls one trait, so it is possible. Currently, the belief is that one gene can interact with other genes to control a trait, and that one gene can control more than one trait.
When a single trait is affected by more than one gene locus this called?
Multifactorial inheritance describes the situation were more than one gene affects a single trait. Environmental factors can also contribute to the single trait.
What is a single gene that affects more than one trait?
Pleiotropy!
Sometimes one gene can influence more than one what?
Trait.
What is a trait called when it is controlled by more than on gene?
Polygenic Traits
Sometimes one gene can influence more than one?
trait :)
What is one difference between a single gene trait and a polygenic trait?
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 mulitple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
What is a trait is called when it is controlled by more than one gene?
Polygenic Traits
Is skin color a quantitative trait?
Skin color is considered a quantitative trait because it is controlled by multiple genes and influenced by environmental factors, resulting in a wide range of variation. This variation is continuous, rather than being determined by a single gene with distinct categories. Quantitative traits typically show a spectrum of phenotypes rather than discrete categories.
How is the gene involved in sickle cell anemia different from the genes for pea plants' traits that Mendel studied?
One gene controlled one trait within Mendel's study, but the sickle cell anemia effects more than one trait.
