Blood types are determined by the type of antigens (protein coating) that you have on the surface of your red blood cells.  \n\nFor the ABO group: \nType A - which has type A antigens\nType B - has type B antigens\nType AB - has both A and B antigens\nType O - has neither A or B \n\nFor the Rh group:\nPositive blood - has the Rh antigen present\nNegative blood - has no Rh antigen\n\nTherefore, type AB+ has all three antigens whereas type O- has none.  There are many other possible combinations (A+, B-, AB-, etc.) depending on the antigens present on the red blood cells.

Most blood transfusions are of packed red cells and not serum/platelets or white cells.  Red cells have no nuclei/genetic material.  Blood type and rH factor are important and mismatch can yield a type of rejection.  The white cells are ultimately "rejected"   In someone with an inactive immune system (chemo patient) the blood can attack the recepient!

O+ 39% \n\nA+ comes in second at 34%\nO+ can be used for all the other + blood types. \n\nOnly 7% of the population has O- but it can be used for all blood types. \n\nDonations go down in the summer months because of vacation travel ...so now is great time to donate blood and save a life. \n\nAll blood types are appreciated and needed but O- and B- blood types are especially needed now.

It has bee several years since I studied blood banking but I think I remember this.  This is a really rare blood type.  To begin with, blood type is determined by antigens on the surface of red cells.  There are two of these antigens, A and B. a person can have one or the other, both or neither resulting in type A, B, AB or O type blood.  Whatever blood type a person has, They have antibodies against the others except for O since it has no antigen.  The antibodies are what make on blood type incompatible with another.  Type O blood is considered the universal donor because there are no antibodies against type O, except in the case of Bombay blood type.  These people actually do have antibodies against type O blood cells.  The condition is extremely rare and very dangerous for those who have it.

Yes.\n\nThis site talks about blood groups in cattle:\n\n"Eleven blood groups have been recognised in cattle - some are simple with only one antigen presented, whilst others are more complicated"\n\nWhat, you thought humans would be unique? =)

Firstly, the idea that your blood will never regenerate is false; blood cells have a life span of thirty (30) days, meaning that your body is constantly regenerating blood anyway.  However, if an individual loses a large amount of blood very rapidly, it is crucial that he or she obtain blood from a donor, because blood cannot be regenerated quickly enough to compensate for a large loss.\n\nSecondly, it is not common to get an O- blood type anywhere, as it is a recessive genotype to all the other blood types.\n\nIf your parents are both type O, then you are most definitely type O.  As for being O- as opposed to O+, it is very rare among families comprising mostly of O+ individuals.  (On the other hand, families with O- always have children with O- until another family member with another blood type joins the family).  However, it is possible if and only if a pair in your preceding family (i.e. great grandparents) were carriers of the O- blood type - this is likely, because you ended up with O- blood type.  There are a much greater handful of O+ individuals who bear O- genes than is apparent, but it's certainly possible; therefore, they are able to pass on those O- genes to their offspring.

So not universal, but definitely most common, by a huge margin.\n\nUniversal would suggest everywhere, and its not true, there is of course AB, A and B blood types also.\n\nYou may be mixing up the term "universal donor", Type O-negative blood does not have any antigens. It is called the "universal donor" type because it is compatible with any blood type. Type AB-positive blood is called the "universal recipient" type because a person who has it can receive blood of any type. Although “universal donor” and “universal recipient” types are occasionally used to classify blood in an emergency, blood type tests are always done to prevent transfusion reactions.

Each blood group is represented by a substance on the surface of red blood cells (RBCs). These substances are important because they contain specific sequences of amino acid and carbohydrate which are antigenic. As well as being on the surface of RBCs, some of these antigens are also present on the cells of other tissues. A complete blood type describes the set of 29 substances on the surface of RBCs, and an individual's blood type is one of the many possible combinations of blood group antigens; usually only the ABO blood group system and the presence or absence of the Rhesus D antigen (also known as the Rhesus factor) are determined and used to describe the blood type. Over 600 different blood group antigens have been found, many of these being very rare. If an individual is exposed to a blood group antigen that is not recognised as self, the individual can become sensitized to that antigen; the immune system makes specific antibodies which binds specifically to a particular blood group antigen and an immunological memory against that particular antigen is formed. These antibodies can bind to antigens on the surface of transfused red blood cells (or other tissue cells) often leading to destruction of the cells by recruitment of other components of the immune system. Knowledge of an individual's blood type is important to identify appropriate blood for transfusion or tissue for organ transplantation.\n\nSeveral different RBC surface antigens stemming from one allele (or very closely linked genes) are collectively labeled as a blood group system (or blood group). The two most important blood group systems were discovered during early experiments with blood transfusion, the ABO group in 1901 and the Rhesus group in 1937. These two blood groups are reflected in the common nomenclature A positive, O negative, etc. with letters referring to the ABO group and positive/negative to the presence/absence of the RhD antigen of the Rhesus group. Development of the Coombs test in 1945 and the advent of transfusion medicine led to discovery of more blood groups. The Coombs test is used routinely in the screening of blood for blood group antibodies in the preparation of blood for transfusion.\n\nBlood types are inherited and represent contributions from both parents. Some blood types are rare, and are primarily found in certain ethnic groups. Some blood types are associated with inheritance of other diseases, for example the Kell antigen is associated with McLeod syndrome. Certain blood types may affect susceptibility to infections, an example being the resistance to specific malaria species seen in individuals lacking the Duffy antigen. Very rarely, a person's blood type changes through addition or suppression of an antigen in infection or malignancy. Transfusion reactions can occur if a person is transfused with blood of a different blood type. Mismatches involving minor antigens or weak antibodies may lead to minor problems; however, more serious incompatibilities can lead to a more vigorous immune response with massive RBC destruction, low blood pressure, and even death.\n\nABO and Rhesus: the two main blood group systems--\nThe ABO system is the most important blood group system in human blood transfusion. The associated anti-A antibodies and anti-B antibodies are usually IgM antibodies. ABO IgM antibodies are produced in the first years of life by sensitization to environmental substances such as food, bacteria and viruses.\n\nThe Rhesus system is the second most important blood group system in human blood transfusion. The most important Rhesus antigen is the RhD antigen because it is the most immunogenic of the five main rhesus antigens; however, anti-RhD antibodies are not usually produced by sensitization against environmental substances. It is common for RhD negative individuals not to have any anti-RhD IgG or IgM antibodies; nevertheless, RhD negative individuals can produce IgG antibodies when they are transfused wit

Rh + is dominant, - is recessive; the A blood type can be either homozygous or heterozygous (its multiple allelles), so babies could be O+ or O-, A+ or A-.

As everyone has told you the only type not possible is O\nbecause to get type 0 blood which is recessive you would need a recessive allele from each parent. Obviously if you are AB (which are codominant) you do not have a recessive allele. The child could Inheret either the A alle or the B allele and would end u p with type A, B or AB blood depending upon the allele passed by the other parent.\nI see you also want to know if there are any blood types not possible for the children of a person with O type blood to get. Yes, a person with O type blood cannot end up with a child with AB blood because they have 2 recessive alleles. They could end up with children with A  B or O phenotypes

There are a number of different cell types in circulation in the blood stream. Here's a quick review:\n\nRed cells carry oxygen to the cells of the body. They are essentially bags of hemoglobin, the oxygen carrying molecule. Hemoglobin binds oxygen to iron atoms, which give the hemoglobin and thus the cells their distinctive red color. \nWhite cells (leukocytes, "clear cells") are divided into two types: \nPolymorphonuclear cells, are of three types: neutrophils, eosinophils, and basophils. \nNeutrophils fight bacterial infection. They form pus and are the chief ingredient of an abscess. See band cells. \nEosinophils are cells which are strongly related to allergy and the recognition of foreign things in the body such as parasites. \nBasophils are cells that are also part of the allergy and parasite recognition system.\nLymphocytes are the virus killers. There are two types of these: \nT-cells which remember what germs we've been exposed to and how to kill them. T-cells are the key component of the immune system that is missing in AIDS. \nB-cells that secrete the actual antibodies that attach to viruses and bacteria and identify them as things to be destroyed - rather like tagging the target with a laser so that the smart bomb will home in and blast the target. \nMonocytes are cells that are related to lymphocytes but have a killing and cleaning function. They cruise through the tissues of the body cleaning up debris and killing any bacteria they find. They are often increased in viral infections - a reassuring finding that your doctor may note on your child's blood count. See mononucleosis. \nPlatelets are the cells that plug leaks in the vascular system, the clotting cells. \n\n What are the different blood groups?   \n   The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.\n\nThere are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.\n\nNobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.\n\n \n\n \n   \n    AB0 blood grouping system   \n    According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).\n\n \n   \n   Blood group A\nIf you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group B\nIf you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.\n\n\n\n \n   \n   Blood group AB\nIf you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.\n\n\n\n \n   \n   Blood group 0\nIf you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.\n\n \n\n \n   \n    Rh factor blood grouping system   \n \n \n   Many people also have a so called Rh factor on the red blood cell's surface. This is also an antigen and those who have it are called Rh+. Those who haven't are called Rh-. A person with Rh- blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance). But a person with Rh- blood can develop Rh antibodies in the blood plasma if he or she receives blood from a person with Rh+ bloo

There are 4 blood types = A,B,AB and O\nIn these blood types the RH is either positive or negative.\nSo there are 8 different blood types.\nAll humans have the same basic blood types, so transfusions are available after they find the blood type of the person needing it. The exception being O-(neg) blood is universal donor, meaning any one can get it, AB- is universal recpient, meaning they can get any blood type.\nAsians are NOT all rh-.
