Explain why type o blood can be donated in a blood transfusion regardless of the recipients blood type?

O Negative is the universal donor.\n\nIndividuals with type O blood have red blood cells with neither antigen, but produce antibodies against both types of antigens. Therefore, a person with type O-negative blood can safely donate to a person with any ABO blood type and is called a "universal donor". However, an O-negative person can only receive blood from another O-negative person.

A, B, and O are the names of specific marker proteins on the blood cells.  A and B are with protiens and O is without.  Positive is indicative of yet another protein, and negative means you don't have it.  The body uses these proteins to identify the cell as 'self', to make sure it isn't a germ.  O negative blood can be accepted by anyone because it does not have any of the proteins that the body would call 'other' and attack.  It is the 'neutral' blood type. The big problem with this, though, is that people with O negative blood can only receive O negative because thier bodies would reject anything else.

Yes, type O is the universal blood type. They can donate to anyone. Their blood cells do not contain the type A or type B proteins on their surface. For people who have type A blood their red blood cells contain only the type A protein so if they were to recieve type B blood, the type A will see the type B as invaders and try to destroy the type B blood. This is because they do not recognize the type B protein because their cells do not have it on their surface. Type O does not have any type A or type B proteins so type A blood cells will accept it.

You can rule out certain blood types, but you can't know the exact one for sure.  For example, you can be sure the father is not either blood type O or B, but he could be A or AB.  The rh factor isn't as easy to figure out.

There are several antigens besides A, B and O that make up blood types, The E antigen is just one of these.  Having the Anti-E antibody means you are negative for the E antigen and at some time in the past been exposed to that antigen.  This is what caused you to produce the antibody.  Healthwise, all it really means to you is that if you ever need blood, it will be screened to make sure it does not have the E antigen so as not to cause any kind of transfusion reaction.  The blood banker who does your type and cross will have to work a little harder but that's all right, belive me, as a blood banker for nearly 20 years, we don't mind at all, we really do want to do every thing in our power to keep our patients safe.

What I think you're saying is that your birth records show that you have type B- blood, but you had a child and now your records show you have A+ blood...is that correct?\n\nIf they are both your blood type, one of them definitely has to be wrong.  Your blood type doesn't change.  This is going to sound odd, but there is a free way to find out your blood type and it helps other people too--you can donate blood.  Of course, you should only do that if you have no diseases that can be passed on to others through your blood.  They will give you a screening at the donor center to make sure you're eligible.  When you give blood at the American Red Cross, a few weeks later they will send you a donor card that has your blood type on it.  Then you'll know your blood type and it's completely free.  Plus your blood donation can help save the lives of up to three people.  That's how I found out my blood type and I have been donating blood ever since.   \n\nAfter you know your blood type, you can start tracking down what's wrong with your records.  Sounds like it's going to be an interesting and complicated process.  Good luck!

in order for a child to have O blood, both parents must have one O allele (because O is recessive so the child needs 2 O alleles). Since we know that the father definitely has one A and the mother has one B, the parents' genotypes are\nmale: AO\nfemale: BO\n\n\nAO x BO\n\n-------A------O\n---B--AB----BO\n---O--AO---OO\n\nI hope you could understand my punnett square; using dashes for spacing is ugly! Their children will have 25% chance of AB blood, 25% A (genotype AO), 25% B (genotype BO), and 25% O.

(1) You can donate even without knowing your Blood Type.\n(2) Blood Group test is performed at almost every hospital. Result is obtained very shortly which allows you to know the type of yuor Blood Group.

The Blood types would have to be 50% chance of Oo and 50% chance of Ao. Remember the three possible alleles in blood are A, B and O, out of the three only O is recessive. So in order to be heterozygous A you have to actually be Ao, If the other allele was a B, it would be AB. Because O is recessive, any individual with O blood type is automatically Oo. The punet squar then looks something like the following\n\n______ Oo\nAo___Ao Ao\n_____Oo Oo, \n\nHope that helps

The most interesting question of the day, so I had to do some research. While I thought it was impossible because of the antigens present in blood types, this article seems to indicate that it can be done. That sure will relieve blood supply issues.

No..."A" and "B" are codominant alelles (gene markers) for blood type, which means they are equally dominant over "O". Type A blood happens when a person either has one A  marker and no marker on the other side (type O), or both A; type AB is when a person inherits one A marker and one B. Type O really means there are "NO" surface markers (antigens) on the red blood cells, which requires that the person inherit type O genes from BOTH parents.  So the genetics would look like this:\n\nMom can be either AA or AO (both express type A)\nDad is AB (can't be anything else)\n\nThus:  Baby can be AA or AB if Mom is AA; baby can be AA, AB, AO, or BO if Mom is AO. But...baby cannot be Type O because OO is not a possible combination when Dad is AB.\n\nSince the blood type doesn't match, positive or negative Rh doesn't matter in determining the paternity.

It is because they want to make sure that the blood is there for them. The blood type is a perfect match for them because the blood is their's. Also, people with rare blood types do it so they would have the blood they need. They don't have to risk anything with a different blood type that could damage them or even kill them.

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

Agree with above: possible options are A+, A-, B+, B-, AB+ and AB-.\n\nTo go into more detail, and explain why a kid with blood type B is possible:\n\nBlood types are named according to proteins in the blood. If you have protein A but not B, you are blood type A. If you have B but not A, you are blood type B. If you have both, you're AB, and if neither, you're O. (O is "recessive" - it just means that you don't make protein, so to be blood type O, you have to have two O genes.)\n\nYou only need one copy of a gene to make the protein, but we all have two copies (alleles) of each gene. We know the dad has to have one A and one B gene. However, the mom could have two A genes, or only one A and one O.\n\nEach parent gives one allele to the child. If the mom has genes AO, she could give the O to the child. The dad has both A and B. So, if a kid ended up with O from mom and B from dad, its genes would be OB and its blood type would be B.\n\nThe Rhesus factor (Rh) + or - is also recessive. If both parents are carrying a negative gene, and the kid got two copies of the negative gene, then it could be Rh-.

The answer is E. For a child to be AB, neither parent can be O, but can be any other blood type.  Keep in mind that each blood type has 2 alleles. The genotype for a B parent can be BB or BO, for A parent AA or AO, or the parent can also be AB. Different combinations of these can create an AB child, but if you have an O parent, that parent is always OO (because O is recessive if you want to look at it that way), and so the child would be either AO, BO, or OO. There's no other choice with an O parent. An O parent only has an O to give, and the AB child needs to get an A and a B, one from each parent.

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-

What?  If you are getting a blood transfusion the doctor will order how many units they want you to receive.  Every unit is not an exact amount.  The amount can vary slightly.  If you had a few extra cc's no big deal - if you were transfused with many units more than you needed, that would be a different story (er nurse).
