ABO blood group in humans depends on the gene I which has three alleles IA, IB and i, hence they show multiple allelism.
Shuffling of alleles by exchange of chromosome segments between non-sister chromatids during production of gametes is called Crossing over. This results in re-arrangement of alleles.
Recombination is a process by which pieces of DNA are broken and recombined to produce new combination of alleles. It creates diversity at the genetic level.
