Why are multiple alleles important?

What is multiple alleles explain with the help of an example?

Multiple alleles refer to the occurrence of three or more than three alleles for a particular gene. Alleles are different or contrasting forms of a gene. For example, for the gene encoding for height, one allele can be for tallness, whereas the other can be for dwarfness.

What do multiple alleles determine?

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 the purpose of alleles?

Alleles are different forms of the same gene which are located on the same part of the chromosome. Genes are made up of information needed to produce different proteins, so alleles carry information to produce different versions of the same protein.

What are multiple alleles and how do they relate to blood types?

In humans and other organisms, there are traits that have three or more different types of alleles (genes). 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.

How do multiple alleles affect inheritance?

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.

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.
