ASO is Allele Specific Oligonucleotide, which is a synthetic DNA probe of 15-21 nucleotides and complementary to the target DNA sequence. So the oligos those could be potentially used in ASO technique to genotype individuals who carry either or both of these above alleles must be complementary in sequence to these alleles. Here among 10 oligos only three are perfect, as their sequences are complementary to the 3' end of those alleles.
