What does the letter i stand for? Someone said it stands for Immunoglobulin. But I looked up immunoglobulins and they are defined as antibodies. But aren't we talking about antigens for the blood type names? For example type A blood would result from genotypes that would be written as IAIA or IAi. Am I right?. I'm confused abut what the letter 'i' actually stands for. Thanks!
@moonbeam2062

I was able to find this text online by someone named Matthew Champion, Staff Scientist with MadSci Network: "There are Two primary alleles for blood type, A and B. There are actually several dozen more, but they are quite rare, and there are even subclasses of A and B themselves. From a Mendelian perspective, the use of the capital letter denotes dominant allele and the lowercase the Recessive. Eye Color is often denoted Bb (Heterozygous Brown) bb (Blue) etc. etc. I cannot locate the first historical use of the letter I(i) for blood alleles, but it is possibly a shorthand for isohemagglutinins, or immunoglobulin type." That still confuses me a little because I looked up both those terms and they both are related to antibodies. So, I'm still not understanding completely why they would be using the first letter of a word associated with antibodies to denote the name of a blood genotype based on antigens. Hmm, oh well, I guess it will remain a mystery, lol.
