What are multiple alleles.give an example
Answers
Multiple alleles exist in a population when there are many variations of a gene present. In organisms with two copies of every gene, also known as diploid organisms, each organism has the ability to express two alleles at the same time.
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. The ABO system in humans is controlled by three alleles, usually referred to as IA, IB, and IO.
pls mark me as the brainliest
Answer :
Any one of a series of three or more allelic forms of a gene, only two of which can exist in any normal, diploid individual.
Example:
The gene of the ABO group system and the hman-leukocyte-asdociated antigen genes.
