There are multiple alleles for the ABO blood group. Why are only two of these alleles present in any one individual?

• Each parent contributes only one allele for the ABO blood group to the offspring.

• There are not enough nucleotides in a red blood cell to produce a third allele.

• Each allele in the ABO group must be dominant or recessive

• Blood group alleles are not segregated during meiosis.
