The mutation seen is most likely due to a frameshift mutation. A nucleotide was added or removed without replacement. This shifted the codon reading sequence by one nucleotide. Therefore the codon downstream of the mutation will code for different amino acids.
THE blood group AB is called the universal receiver because any other blood group can be compatible with this blood group this is due to the absence of anti-bodies in this type
while blood group O is called the universal donor because it is compatible with all blood groups due to the absence of antigen (A and B)
while blood group A receives blood from itself and O and donates blood to itself and AB thesamethinggoeswithbloodgroupB
