Introduction:

The allele is the form of a single gene present in an organism. The different combination of the alleles determines the genotype and phenotype of the organism. The allele can be of two types dominant or recessive. The dominant allele has a property to mask the effect of the recessive allele in heterozygote condition. The ABO blood grouping is an example of the multiple allele trait.
