WebNov 22, 2024 · People can be divided into four main groups (A, B, O, and AB) based on the agglutination patterns of their red blood cells. The ABO blood group system consists of A and B antigens on red blood cells and their … WebOct 23, 1997 · If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B ...

WebThe two common H phenotypes are "secretor" and "non-secretor". Secretor (common) H antigen is expressed on RBCs. H antigen is expressed in saliva. No anti-H is produced. Genotype: H/H or H/h; Se/Se or Se/se Non secretor … WebJul 28, 2024 · There are four major blood groups: A, B, AB and O. These are determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. There is also a protein called the Rh factor, which can be either present (+) or absent (–), and this creates the eight most common blood types ( A+, A-, B+, B-, O+, O-, AB+, AB- ). WebSep 28, 2024 · Humans can have red blood cells that are of type A (I A ), type B (I B ), or type O (i).
