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 an example of multiple alleles trait?
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 is an example of multiple alleles trait 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.
|Genotype||Phenotype (blood type)|
What is meant by some genes have multiple alleles?
Multiple alleles is a type of non-Mendelian inheritance pattern that involves more than just the typical two alleles that usually code for a certain characteristic in a species. … Other alleles may be co-dominant together and show their traits equally in the phenotype of the individual.
Is eye color an example of multiple alleles?
Yes, eye colour is an example of multiple alleles. They are more than two alleles encoding for the same.
What is an example of a polygenic trait?
A polygenic trait is a characteristic, sometimes we call them phenotypes, that are affected by many, many different genes. A classic example of this would be height. Height in humans is very strongly genetically controlled, but there are many, many different genes that control height.
Which trait is normally controlled by multiple alleles?
The ABO blood group in humans is a trait controlled by a single ABO gene with three types of alleles (multiple alleles) are seen. The ‘a’ and ‘b’ alleles express codominance.
What are the three alleles that control human blood type?
The four main blood groups A, B, AB, and O are controlled by three alleles: A, B, and O. As humans are diploid, only two of these can be present in any one genotype.
