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.
Which of the following is controlled by multiple alleles?
The main particular gene adjusts in three or four allele forms known as multiple alleles. -Example of multiple genes is the genes of ABO blood group system. -The ABO system in humans is controlled by three alleles usually referred to as Ia, Ib and Ic.
Which of the following is an example of multiple alleles?
An example of multiple alleles is the ABO blood-type system in humans. In this case, there are three alleles circulating in the population.
What is caused by multiple alleles?
Multiple alleles combine in different ways in a population, and produce different phenotypes. These phenotypes are caused by the proteins encoded for by the various alleles. Although each gene encodes for the same type of protein, the different alleles can cause high variability in the functioning of these proteins.
What are multiple alleles?
Alleles are described as a variant of a gene that exists in two or more forms. Each gene is inherited in two alleles, i.e., one from each parent. Thus, this means there would also be having two different alleles for a trait. … These three or more variants for the same gene are called multiple alleles.
Where are multiple alleles present?
Multiple alleles are present at the same locus as one type of chromosomes. The pairs of genes occupying a specific spot called locus on a chromosome are known as alleles.
What are multiple alleles give any two examples of multiple alleles?
Examples 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 is multiple allele with example?
The major example of multiple allelism is ABO blood grouping in humans. Complete answer: Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. … Allele A codes for antigen A, Allele B codes for antigen B, and Allele O codes for the absence of antigen.
What is multiple alleles and co dominant alleles?
Whenever a given trait has three or more different alleles, we say that the trait has multiple alleles. One example of a trait the has multiple alleles is the human ABO blood group trait. … These three alleles that constitute the ABO blood group trait observe a pattern of inheritance called codominance (co-dominance).
What are multiple alleles quizlet?

Multiple Alleles. – When three or more alleles control a trait. Example. Blood Types in humans.
What is an example of multiple allele inheritance?
Examples of Multiple Alleles
The human ABO blood type is a good example of multiple alleles. Humans can have red blood cells that are of type A (IA), type B (IB), or type O (i). These three different alleles can be combined in different ways following Mendel’s Laws of Inheritance.
What is an example of multiple alleles traits What are the alleles that control that trait?
The majority of human genes are thought to have more than two normal versions or alleles. Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type.
Multiple Allele Traits.

What are multiple alleles in Class 12?
Category : 12th Class. More than two alternative forms (alleles) of a gene in a population occupying the same locus on a chromosome or its homologue are known as multiple alleles.
