Jarind's Letters First found since 1987,

Let capital letter be dominant gene and
small one be recessive gene. We also let unlabeled letter
(Jarind's) be normal gene and labeled letter(Sims') with
number be abnormal one.
Let gene A as letter A = Blood group A,
B or E = Blood group B,
then o and other remained letters = group o,
( Genotype Blood gr. O =oo or aa or bb or ab or non A , non B & non E  letters etc.)
Au = subgroup Auberger,au = Auberger negative,
Ca = subgroup Cartwright, ca = Cartwright negative,
Co = subgroup Colton, co = Colton negative,
C,D,E = subgroup Rh(D = Rh positive),
Da = subgroup Diego a+,da = Diego a-,
De = subgroup Diego b+,de = Diego b-,
Do = subgroup Dombrock,do = Dombrock negative,
Fa = subgroup Duffy a+,fa = Duffy a-,
Fe = subgroup Duffy b+,fe = Duffy b-
H = secretor(H- antigen in saliva of secretor),
h = nonsecretor,
K = subgroup Kell +,k = Kell -,
Ka = subgroup Kidd a+, ka = Kidd a-,
Ke = subgroup Kidd b+, ke = Kidd b-,
La = subgroup Lewis a+, la = Lewis a-,
Le = subgroup Lewis b+, le = Lewis b-,
L = subgroup Lutheran a+, l = Lutheran a-,
Lu = subgroup Lutheran b+, lu = Lutheran b-,
M,N,S = subgroup MNSs system (group M,N,MN,S,s),
P = subgroup P1,p = subgroup P2,
Sa = subgroup Scianna, sa = Scianna negative,
Si = subgroup Sid, si = Sid negative,
X  = subgroup Xg( X-linked dominant)
We use capital letters for genes of blood groups which
are positive antigen detection, others are n't then let's use
small cases or we can use no letter for negative blood group
antigen.That means we can leave with no mention of
represent letters in negative antigen of blood grouping.
