Another type is autosomal recessive, in which an individual must receive a copy of the gene from both parents in order for the gene to be expressed. The type concerning blood groups is codominance and it is when two different versions of a gene are expressed. Both of the alleles have a role in the appearance of the characteristic. Both the A blood group and B blood groups are dominant; however, if both alleles are present, the individual has an AB blood group.</span><span />
