WebMay 29, 2024 · Our ABO blood type comes from a stretch of DNA (called the ABO gene) that has the instructions to make these different sugars. Depending on which instructions your DNA has, you’ll make a certain combination of these antigens - this creates your blood type! If you’re interested in how we inherit our ABO blood type, take a look at this post. Web15.3: ABO typing by molecular genetics. Whereas ABO typing by serological means is straightforward and extremely accurate, the genetics of ABO is complex, rendering ABO molecular typing by available methods unreliable. This is particularly so in people of African origin, where hybrid ABO alleles are present. As it is never acceptable to obtain ...
