How to solve ABO blood group frequency problems

Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient’s immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching. There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present ( ) or absent (–), creating the 8 most common blood types (A , A-, B , B-, O , O-, AB , AB-). #ABOBloodType #BloodGroup #AlleleFrequency #GenotypeFrequency #ABOBloodTypes #ABOBloodGroups #RhBloodGroups #blood #classification #antibodies #transfusion #incompatibility #rhesus #bloodGroupsAndBloodTypes #bloodGroupsExplained #bloodGroupsAndTransfusions #bloodGroupsVideo #aboBloodTypesExplained #aboBloodGroupSystem #aboBloodTyping #aboBloodGroup #bloodTransfusion #bloodTransfusionNursing #bloodTypeCompatibility #bloodTypesAndRhFactor
