Even if a character shows multiple allelism, an individual will only have two alleles for that character. Why?

Explanation

Multiple alleles are the multiple froms of a gene which occur on the same gene locud, but distributed in different organisms in the gene pool with an organism, which carry only two alleles anf the gamete have only one allele.
Despite multiple allelism, an individual will have only two alleles becaus an individual develops from a ztgote whihc is the result of fusion of sperm (carrying father set of (n) haplid chromosomes) and an egg (varrying mother set of haploid chromosomes).
Sperm and an egg have only one gene (allele) for each teait. A zygote when because dipoid, have two alleries for each trait. It is the maximum number of alleles an individual can have. e.g., genes of blood groups.
