I have Blood group A negative, Which all Blood types can I accept ?

Without pasting a book in here from another webpage and without adding info that you didn't ask for: you can accept A and O, anything other than that will kill you. The existing blood will attack the new blood.

Your blood type depends on the blood type of your parents. So if their bloodtype is known you can make a good guess of your bloodtype. \nBut to be ascertain you'll have to get pricked .. Btw .. it doesnt hurt or something .. they just take a droplet of your blood for this test ..

antigen B is on their cells, and antibodies against antigen A are produced in their serum. Therefore, a group B person can only receive blood from people in groups B or O, preferably B.

it is very simple \nif ur blood type is o+ than u can receive blood from o+ and o-\nif ur blood type is o- than u can only receive blood from O-

oh my god - some of these answers are scary.\n\nthe question is very excellent though and very correct. the anti-A and anti-B CAN destroy the patients red cells if transfused to a group A or group B or group AB individual.\n\nhowever:\n\nthe antibodies are in the plasma and modern practices in blood processing split the components into their various parts - plasma and platelets and red cells. the red cells has very little plasma on them so very little anti-A or anti-B is transfused\n\ndonations with plasma on them are tested to see if the levels of anti A or anti B might be considered harmful and those donations with high titre (levels) of anti-A or anti-B are marked as not for transfusion to group A or B or AB patients.\n\nthe term universal donor is a very misleading one, in general it is true and group O can give to any other group, but precautions are necessary and are taken by transfusion services

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

no doesnt matter as far as blood groups go. AB, B, O whatever theyre all just as good. \n\nhowever, genetic testing to see if people carry a rececive gene that could result in diseases like cystic fibrosis or tay-sachs might be a good idea.... but you could always adopt or hope your kids dont get those diseases, so i wouldnt look to far into it. plus you might scare off your girl if you make her get all kinds of blood tests before you get married

on red blood cells there are two major antigens A and B among other minor antigens.these designate one's blood group.\nBlood group O is indicative of one having no blood group antigens on his/her red blood cells.\nfor any blood group antigen there's a corresponding blood group antibody in the blood fluid i.e plasma or serum.for example if you are blood group A then your blood will have antibody B,if you have blood group B then you have antibody A.however if one is blood group O then that means that you have both antibodies A and B,and if you are blood group AB then you have no major blood group antibodies i.e neither antibody A nor B is present in your plasma.now if a blood group A person receives any blood group other than A or O then the antibodies in the plasma cause clumping(coming together)of the foreign blood cells.this causes blocking of the blood vessels with disastrous results.please note that it's the foreign blood cells that are clumped by the native antibodies if they match i.e A with Antibody A,B with antibody B,O with either A or B and AB by none.for this reason O can donate blood to any blood group but cannot receive blood except from another O and AB can receive blood from anyone but cannot donate their blood to anyone except AB.there is another group of antigens known as the rhesus factors.one is either rhesus positive(+) or negative(-).therefore a blood group O+ can donate blood to any rhesus+ blood group and blood group AB+ can receive any rhesus+ blood group.hence to answer your question blood group O can take blood only from an O of the correct rhesus factor

yes\notherwise known as universal donor\na person with this blood type could only take blood from exact same group.\n\nab+  universal recipient =  can take blood from any group but can give blood only to same group.

I am a nutritionist.....We all have a blood type, try and find out yours, then follow your  record..... although also use the common sense version, such as....sode, fries, andything fried, candy, sweetes, although these are bad, you can eat them on accations. Not daily, hourly and secondly.

It is not possible for a child of two O+ parents to have A+ blood.\n\nThe Rhesus factor (Rh) positive is not a problem - only one parent has to be positive.\n\nHowever, blood groups A, B, AB and O are determined by autosomal dominant transmission - this means that you only have to have one copy of the gene in order to express the trait, and they are not on the sex chromosomes, so both male and female children have equal chances of getting them.\n\nThe "A" and "B" just refer to two different proteins, called A and B (surprise). If you have one copy of the gene, YOU WILL HAVE THAT BLOOD TYPE. The only way to have O blood is to have two recessive O genes. Both parents *have* to be genotype OO. If they have one O and one A gene, then they will be blood type A.\n\nSo, if both parents are O, the ONLY possible blood group for their children is O. If the mother is O and the child is A, the father MUST be A.

Your genotype determines your blood type before your born. There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO. In addition to the proteins (agglutinogens) existing on your red blood cells, other genes make proteins called agglutinins (a-GLOO-tin-ins) that circulate in your blood plasma. Agglutinins are responsible for ensuring that only the blood cells of your blood type exist in your body. People who have an AA genotype are said to have type A blood because the agglutinogen on their red blood cells has the enzyme activity associated with the A allele. It is important to recognize that people with the AO genotype also have the enzyme activity associated with the A allele, so they are also said to have type A blood. People with the BB and the BO genotypes are said to have type B blood. People who have the AB genotype have the enzyme activity associated with both the A and B alleles. These people have no agglutinins in their blood plasma.  In the case of blood type, both the AA and AO genotypes cause individuals to display the A blood type phenotype. Similarly, both the BB and BO genotypes cause individuals to display the B blood type phenotype. Individuals who are phenotypically type O or type AB have only one possible genotype, OO and AB, respectively. In different parts of the world, the fraction of individuals with blood type A, B, O, or AB differs. The frequency with which blood types are observed is determined by the frequency with which the three alleles of the ABO gene are found in different parts of the world (allele frequency). Variation in the allele frequency at the ABO gene reflects the social tendency of populations to marry and reproduce within a national, regional, or ethnic group. As people throughout the world intermingle to a greater extent, the distribution of the different blood types will become more uniform throughout the world. Hopefully that helps a bit!

http://gslc.genetics.utah.edu/units/basics/blood/types.cfm\n this explains both questions. at the bottom of the page there is a link to "what is a blood transfusion" it tells you how it works too.

Then your only option is to get a blood test.  If you donate blood, they will tell you your type, plus you will be helping a great cause!

There is no such thing as worst type of blood. The only blood one would not like to have is the one which cannot coagulate and of-course blood tainted with HIV and other infections.

O pos, A pos, B pos are the most common. Next is O neg, A neg, B neg. All RH neg blood is considered rare but the most rare are AB pos and AB neg. If you are a female with a negative RH factor and you become pregnant from a man with a positive RH factor, you will need a shot or your body will reject the pregnancy and you could lose the baby. If he is negative also, the baby should be fine. If the female is postive she can carry a baby with negtive blood type just fine. The blood type O pos can go to any POSITIVE blood type, O neg can go to any NEGATIVE blood type. O pos can only receive O pos, and O neg can only receive O neg.
