The inheritance of human blood types (abo) is influenced by multiple alleles dominance codominance all of the above are correct.

The inheritance of human blood types (ABO) is influenced by codominance

Codominance is when a child receives an A allele from one parent, and a B allele from another, thus the offspring receives traits from both parents equally, rather than having one dominant gene, say the father, making the offspring color different, etc.
