Blood type in humans is determined by a single gene that has multiple alleles?

Each person has two alleles for their blood type, one dominant and one recessive. Except for type AB blood where the alleles are co-dominant. The allele for O blood is always recessive when paired with either an A or B allele.

What are multiple allele traits?
A polygenic trait that require the additive effects of many alleles to be expressed. Height is an example of a polygenic trait. Or, a trait that has many alleles to fill the loci on chromosomes. Blood types are examples of this. A, B and O are all alleles that git the two chromosomal loci, but only any two at once whether homozygous or heterozygous.
What are inherited traits of fruit flies?
eye color (red/white) and body color (brown/yellow). In fruit flies, eye color is a sex-linked trait determined by a single gene with two alleles. Red color is dominant to white eye color. Body color is an autosomal trait determined by a single gene with two alleles, where brown is dominant to yellow. -Angela B.
What is monohybrid inheritance?
Monohybrid inheritance is where an individual inherits a characteristic which is determined by a single gene with two alleles. For Example: coat color in specific mice is determined by one coat color gene with two alleles B ( black fur) and b ( for brown fur) As you can see one is dominant (B) and one is recessive (b).
Is huntington's disease determined by multiple alleles?
No. This is a single gene disorder. If at least one allele has the huntington's mutation, the person will eventually develop the disease.
What are traits inherited by multiple alleles?
Traits inherited by multiple alleles are those that are controlled by three or more different forms of a gene (alleles) at a single locus. Examples include human blood type, where the ABO gene has three common alleles (IA, IB, and i), and coat color in rabbits, which is determined by four alleles of the C gene (C, cch, ch, and c).
What is the multiple allele system?
The multiple allele system refers to a genetic system where a particular gene has more than two alleles present within a population. Each individual carries a maximum of two alleles for a gene, but the population as a whole may have multiple alleles. An example of this is the ABO blood group system in humans.
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.
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.
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.
Is the three alleles of the single gene that controls blood type is said to be what alleles?
The three alleles of the single gene that controls blood type are typically referred to as A, B, and O. The A and B alleles are co-dominant to each other, while the O allele is recessive to both A and B.
Which is most inclusive A. Allele B. Genotype?
single genes wiht multiple alleles
What is the difference between a single gene and a polygenics trait?
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc

How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
