Is Blood Type A Polygenic Trait

A polygenic trait is one whose phenotype is influenced by more than one geneTraits that display a continuous distribution such as height or skin color are polygenic. Polygenic traits are a type of non-Mendelian inheritance.

A polygenic trait is one whose phenotype is influenced by more than one gene.

Is blood type a polygenic trait. Сorrect answer to the question. Monogenetic traits are single gene traits. A trait is said to be polygenic when more than one genes control the expression of the particular trait such as hair colour eye colour.

Which of the following is not a polygenic trait. Answered Apr 22 2017 by Dr-Jivago. Is skin color a Mendelian trait.

What is the genotype of the child. Traits that display a continuous distribution such as height or skin color are polygenic. ABO blood type b.

The two alleles for A and B antigens on the red blood cells of blood type AB individuals are dominant and therefore are expressed together. Traits that display a continuous distribution such as height or skin color are polygenic. There are three alleles present for the gene I.

Each of them produces an effect that adds up to the trait. Asked Apr 22. Blood type AB in humans for instance is not a polygenic trait.

Rather it is a case of codominance. An example is one womans single gene trait for blood type. One gene controls the expression of a specific structure protein or function.

Except for some rare special cases the humans can only fit into one of four categories for the ABO part of their blood type. What are Polygenic Traits. In a system which differs from Mendelian Genetics where monogenic traits are determined by the different alleles of a single gene polygenetic traits may display a range of possible phenotypes.

Each biological parent donates one of two ABO genes to their child. Since the ABO part of your bloodtype fits neatly into four categories it is a qualitative trait. These genes are called polygenes.

Is blood type A monogenic trait. Learn vocabulary terms and more with flashcards games and other study tools. A B AB or O.

The polygenic traits show a continuous variation of the character. Each gene is located in different loci of different chromosomes. The blood type gene is located on chromosome 9 locus is 9q34.

Which of the following human traits is not a polygenic trait. Is O blood recessive. Is blood type a polygenic trait.

Blood type is an example of multiple allelism. Answered Apr 22 2017 by. The Polygenic and Monogenic Basis of Blood Traits and Diseases Blood cells play essential roles in human health underpinning physiological processes such as immunity oxygen transport and clotting which when perturbed cause a significant global health burden.

People who inherit B alleles make B sugars and have type B blood. What is the genotype of the child. You can often represent qualitative traits with.

What does a polygenic trait mean. Start studying blood types polygenic traits califf. Thus polygenes show incomplete dominance.

A trait that is controlled by more than one gene is referred to as a polygenic trait. A polygenic trait is one whose phenotype is influenced by more than one gene. Polygenic inheritance also known as quantitative inheritance refers to a single inherited phenotypic trait that is controlled by two or more different genes.

A child with type O blood is born to a mother with type A blood. Just like eye or hair color our blood type is inherited from our parents. Polygenic trait refers to a trait that is controlled by multiple non-allelic genes.

An individual contains a pair of alleles which determine the blood type. A child with type O blood is born to a mother with type A blood. Polygenic Inheritance Definition.

They are a group of genes that when turned on they are expressed as a unit. A polygenic trait is a trait in which the phenotype is controlled by more than one gene.
