Multiple Alleles- Blood Typing
How common is your blood type?
46.1%38.8%11.1%3.9%Genetics of Blood TypesHuman blood type is determined by co-dominant allelesAntigens-proteins-exist on the surface of all of your red blood cells.
Blood typesFor simplicityIAAIBBiOAntibodiesFound in the plasmaSpecific to a single kind of antigenAttack and kill that specific kind of antigen
What are blood types?
http://learn.genetics.utah.edu/units/basics/blood/types.cfmThere are 3 alleles for blood type: A, B, O Since we have 2 genes: 6 possible combinationsBlood TypesAA or AO = Type ABB or BO = Type BOO = Type OAB = Type AB
RBC= Red Blood Cell = antibody
Antibody B- protects the body by attacking foreign B antigen blood
Scenario B
Scenario ABScenario O
Blood TransfusionsBlood transfusions used to replace blood lost during surgery or a serious injury or if the body can't make blood properly because of an illness.
ABOABWho can give you blood?
TYPE O -Universal Donorscan give blood to any blood typeNo antigens present on RBC
TYPE AB- Universal Recipients can receive any blood type No antibodies present in plasma
Universal DonorUniversal RecipientRh FactorsRhesus monkeys contain certain similarities with humansA blood protein was discovered and present in the blood of some peopleThe presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor.
Rh positive (Rh+) - contain the proteinRh negative (Rh-)- NOT contain the protein
