what does the "I" stand for in genetics and in the blood typing?
92766
The "I" stands for the isoagglutinogen gene.  Everybody has two copies of this gene, but know that this gene can come in different "flavors", what scientists call "alleles".  These flavors are Ia, Ib and Io.  The "I" indicates a single gene, and the a,b and o indicate the different versions, or "alleles", of this gene.  The "o" is termed recessive, because it "invisible" to the immune system, while "a" and "b" are dominant, meaning the immune system can identify and react with them.

An allele.  Alleles can be dominant or recessive.

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.

I've not seen this notation before but I'd guess it stood for 'Immunoglobulin'

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 ..

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.☺

The easiest way to understand it is to look at a picture. There's one in the source link at the bottom that has a chart so you can look up both parents and find out about the child. The site also explains why ABO blood typing is not an absolutely reliable test of parenthood, and it explains how the rh factor (the + or -) works. The baby does not have to be the same as either of its parents. Be careful. A lot of people who think they understand this really don't.

Blood type has to do with chemical markers on your cells called antigens. People with type A blood have A antigens, and people with type O blood have no antigens. A person has two genes controlling blood type, one from each parent. Both your parents have the genotype AO. Because they have the gene for A, they produce the antigen for that blood type. However, you inherited the recessive gene from both your mother and your father (genotype OO) and therefore have no antigen-producing genes. This makes you type O.  \n\nTherefore, if your spouse also has type O blood, then any chidren you produce would also have to be type O. The person above me is either mistaken about her parents' bloodtypes or the identity of her parents.\n\nThe RH factor (+/-) works in a similar fashion.

Genotype is the description of the alleles an individual possesses for a particular trait. (ex: Bb)\nPhenotype is the physical expression of the alleles - what an organism looks like. (ex: Blue eyes)

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-.

Rh simply means Rhesus.  When we are born we recieve 3 rhesus genes from each of our parents that make up what our blood time will eventually be.\n\nSpecifically:\n\n'We all inherit a set of three Rhesus (Rh) genes from each parent called a haplotype. You may have heard of the c, d, e, C, D and E genes. The upper case letters denote Rh positive genes and the lower case, negative and we inherit either a positive or negative of each gene from each parent (eg. CDe/cde, cdE/cDe etc.). This means that we then possess two of each gene and can pass either to our offspring.

The E "antigen" is part of the Rh complex (the + part of your blood type). Try the website below for more info on the Rh complex. Hope this helps.

The blood types are A, B, AB, and O. Additionally, you can either be Rh+ or Rh-\n\nso in total the blood type possibilities are\nA+\nA-\nB+\nB-\nAB+\nAB-\nO+\nO-\n\nhope that helps.  If you are looking for the genetics codes thats different....be a little more specific in that case...
