They are usually a result of mutations in genes that are essential for growth or development.

•Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist in a population level, and different individuals in the population may have different pairs of these alleles.
• Gene mutations may produce many different alleles of a gene
 • All such altered alterriative forms of a gene, whose number is more than two, are called multiple alleles.
 • Any two of these multiple alleles can be present in the genome of a diploid organism, but a haploid organism or a gamete can have just one of them in its genome.
•In human population, one of examples of multiple allelism is inheritance of ABO blood types involving three alleles (I, I^A, I^b).
