What is an example of a multiple allele trait in humans?

Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. Your blood type refers to which of certain proteins called antigens are found on your red blood cells.

What is the most common example of multiple alleles?

Two human examples of multiple-allele genes are the gene of the ABO blood group system, and the human-leukocyte-associated antigen (HLA) genes.

What are 2 examples of polygenic traits?

In humans, height, skin color, hair color, and eye color are examples of polygenic traits. Type-2 diabetes, coronary heart disease, cancer, and arthritis are also deemed as a polygenic. However, these conditions are not just genetic since polygenes can be influenced by environmental factors.

Why is human blood type an example of multiple alleles?

An example of multiple alleles is the ABO blood-type system in humans. In this case, the IA and IB alleles are codominant with each other and are both dominant over the i allele. Although there are three alleles present in a population, each individual only gets two of the alleles from their parents.

Are multiple alleles common in humans?

Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist in a population level, and different individuals in the population may have different pairs of these alleles.

Why is multiple allele trait described as such?

Traits controlled by more than two alleles have multiple alleles. Although any one person usually has only two alleles for a gene, more than two alleles can exist in the population’s gene pool. Theoretically, any base change will result in a new allele.

What traits have multiple alleles?

The best characterized example of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian Inheritance concept. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structures, etc.

What does multiple allele mean?

Definition of multiple allele : an allele of a genetic locus having more than two allelic forms within a population.

Is multiple allele common in human?

Although humans (and all diploid organisms) can have only two alleles for any given gene in genetics, multiple allele traits may exist at the population level.

What does it mean for a trait to have multiple alleles?

Definition and Examples With multiple alleles, that means there are more than two phenotypes available depending on the dominant or recessive alleles that are available in the trait and the dominance pattern the individual alleles follow when combined together.

What trait is controlled by a gene with multiple alleles?

A trait controlled by one gene but multiple alleles is blood type. There are 4 phenotypes: A, B, AB, O. Types A and B are codominant, and O is recessive to A and B.

What does it mean if a trait has multiple alleles?

With multiple alleles, that means there are more than two phenotypes available depending on the dominant or recessive alleles that are available in the trait and the dominance pattern the individual alleles follow when combined together.

What is an example of a trait with multiple alleles?

Multiple Alleles: The ABO blood type of humans is an example of a trait determined by multiple alleles. Polygenic Traits: The kernel color in wheat and corolla length in tobacco are the examples of polygenic traits in plants.

What is the difference between polygenic and alleles?

Polygenic Traits: Polygenic trait is a trait that is controlled by a group of nonallelic genes. Multiple Alleles: Only two types of alleles are present in an individual; multiple alleles can be found within the population. Polygenic Traits: All polygenes can be found in the individual.

Which of the following is an example of non-Mendelian inheritance pattern?

Both multiple alleles and polygenic traits are the examples of non-Mendelian inheritance patterns. More than two factors are involved in the determination of a trait in multiple alleles and polygenic traits. Multiple Alleles: Multiple alleles refer to a series of three or more alternative forms of a gene.

What is the difference between the A and B alleles?

The A allele and the B allele are equal in their dominance and will be expressed equally if they are paired together into the genotype I A I B. Neither the A allele or the B allele is dominant over each other, so each type is expressed equally in the phenotype giving the human an AB blood type. Scoville, Heather.
