ALL of them.\n\nSheesh.

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 ..

just like any other trait, the baby can inherit the blood type from either the mother OR the father.\n\nHere's a link that shows possibilities for the baby depending on each parents blood type:\nhttp://mistupid.com/health/bloodinherit.htm

O+ is the most common, AB- is the rarest. \nOverall, the O blood type is the most common blood type in the world, although in some areas, such as Sweden and Norway, the A group dominates. The A antigen is overall more common than the B antigen. Since the AB blood type requires the presence of both A and B antigens, the AB blood type is the rarest of the ABO blood types. There are known racial and geographic distributions of the ABO blood types.\nFor more info refer to the source - wiki.

Genetic variation or differences would be the primary factor to give this question an explanation.  The same explanation that tells why there are different eye colors, different hair, different skin colors, etc. We inherit our blood type from our parents. Genes on our chromosomes tell the body what type of blood to make.\n\nThe types of proteins, glycoproteins and glycolipids found (or expressed) on the surface of red blood cells define blood types. In addition, blood types, or at least the genes responsible for them, are inherited. Karl Landsteiner described the original blood types - A, B and O - in 1900 and doctors now recognize 23 blood group systems with hundreds of different "types." Many of the blood type antigens (and the antibodies that react with them) have been discovered as a result of transfusion incompatibilities. Some of these molecules have additional functions that are at least as important as conferring compatibility (of lack of compatibility) on transfusion recipients. \n\nThere are four popularly known blood types: A, B, AB and O. These designations refer to the types of sugars (A, B and O) found on the surface of red blood cells. Everyone on the planet has an O sugar, and those who have no other type are known as blood group O. The other group names arise from the fact that some people have A, B or both A and B sugars attached to the O sugar.\n\nThe genetics is unusual in that there are two equally dominant alleles. If the gene from your mother is the recessive allele for producing O cell surface markers, and the gene from your father is for A cell surface markers, then your overall blood type is A. Why? Since everyone has O we only look at the second sugar present to determine blood type. If the gene from your mother was for B and the gene from your father was A, then your blood type would be AB. If both parents donated A alleles, then you would be A. And if both gave you recessive alleles then your blood type would be O.\n\n>> If we have the genes for the A antigen, we will make red blood cells that have A on them.\n>> If we inherit A antigen from both parents or A from one and neither A or B from the other we will have group A blood. \n>>If we inherit B antigen from both parents or B from one and neither A or B from the other we will have group B blood. \n>>If we inherit A antigen from one parent and B from the other we will have group AB blood. \n>>If we inherit neither antigen from both parents we will have group O blood. There is no O antigen. O is the result of not having any A or B. \n>>In addition to our blood group (A,B,AB,O) we can inherit the D antigen. D is more commonly know as the Rh type. This is what is called the positive or negative. Either we have it or we don't. \n>>If we inherit Rh antigen from both parents or Rh from one and not from the other we will have type positive blood. \n>>If we do not inherit the Rh antigen from either parent we will have type negative blood.\n\nThere is no much elaboration on non - ABO blood type as there is only a few who got any of the rare identified blood types.☺

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.

The children would have bloodtype A or bloodtype B.\n\nThe "O" which they get from one parent is merely an absence of the information necessary to have specific antibodies against other bloodtypes.

Different kinds of animals have different kinds of blood. Dogs have 4 blood types; cats have 11; cows have about 800.

Here is some information I found on the web...hope it helps, good luck!\n\nIn the former USSR and Russia, blood types are referenced using numbers and Roman numerals instead of letters. The conversion from one to the other is as follows:\n\nConversion Chart USSR Designation Common Designation \nGroup I (1) O \nGroup II (2) A \nGroup III (3) B \nGroup IV (4) AB

hehe. Something is amiss.  \nO is recessive. A and B are codominate.\nTo be true O, your genotype is OO.\nTo be B, your genotype is BB or BO.\nTo be A, your genotype is AA or AO.\nTo be AB, your genotype is AB.\nSo one of your parents have to have B allelle.  If either of your parents are OB (then in reality one of your parents is blood type B not O.), then it is possible that you are blood type B.\n\nIf not, well, your patients raised you and you consider them your parents.  Does it really matter that one of your parent is not you biological parent.  Talk to them.  Be patient and they may explain things to you when you get older.

Blood group is highly related to genetics. It is possible to have an O child even if both parents are not O.\n\nIf the parent's are both a heterozygote, then there is 1:3 chance that the child get an O blood group. However, if at least one of the parents are homozygot, then it's impossible.\n\nAbouth the two Rh+ become Rh-. It's also possible, since it's basically the same as the ABO blood group, if the Rh+ parents are heterozygots then it's possible to have a child of Rh-. \n\nSo:   \nBO +- >< BO +-\ncan have a \nOO --\nchild.

Codiminance is when two alleles are expressed in a trait. For blood type, your father may be type A and mother Type B...There is thus (if they are homozygous dominant) 100% chance you will have blood type AB. This means both A blood cells and B blood cells are present in your blood, but they do not fight or compete with one another as they wouold if Type B blood were to be introduced to a Type Blood A person.

Can a man have, let's say, B+? Yes.\nCan a woman have, let's say, B+? Yes.\nCan they get married? Yes.\n\nExact same blood type will not be a problem. Only way for problem is if baby is + and mom is -. Only way for that to happen is if Dad is + and mom is -.

There are 200 types of arthritis. The majority of types of arthritis are not hereditary. However, if you have a condition that is hereditary – like sticklers syndrome – you will be aware of this as your doctors will be monitoring your condition closely. \n\n\nRecent evidence suggests that certain types of arthritis such as osteoarthritis in the hands can be hereditary, but further studies are needed to confirm this. \n\n\nSome people may have a genetic preposition to certain types of arthritis (lupus, ankylosing spondylitis etc), but this is not the same as a type of arthritis being hereditary.

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.

The main blood types are A, AB, B, and O.  These blood types are fromed due to a specific type of protein found on the red blood cells.  A type blood has A protein, while B has B protein.  O does not contain any protein so the O stands for zero.  AB contains both A and B proteins.  Along with this there is the Rh positive and negative type.  This is independent of the ABO grouping so  you can have all the ABO types plus the positives and negatives as well.  So far ther are 8 distinct types.  Along with this there is a M and N type.  This is more subtle and it is usually not tested for. So now we have 16 different types possible.
