Detailed explanation-1: -Alleles are the pairs of genes occupying a specific spot called locus on a chromosome. Typically, there are only two alleles for a gene in a diploid organism. When there is a gene existing in more than two allelic forms, this condition is referred to as multiple allelism.
Detailed explanation-2: -Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. Your blood type refers to which of certain proteins called antigens are found on your red blood cells.
Detailed explanation-3: -Multiple alleles are present at the same locus as one type of chromosomes. The pairs of genes occupying a specific spot called locus on a chromosome are known as alleles. Generally, in a diploid organism, there are only two alleles for one gene.
