What is the frequency of blood?

On the basis of our previous work, the electric frequency property of human blood in different components, in physiological state and in pathological state (diabetes) are tested and analyzed in the range of 1Hz-20MHz progressively.

Which blood type has the highest frequency?

Blood group O
Blood group O has the highest frequency while blood group AB has the lowest frequency (Table 1).

How common is ABO blood type?

O-negative (6.6 percent) B-positive (8.5 percent) A-positive (35.7 percent) O-positive (37.4 percent)

Which ABO is most common?

Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.

How do you find the frequency of a blood group?

Based on this formula, the allele frequencies of the ABO blood groups in the population was as follows: the frequency of the Io allele (r) = 0.6052 the frequency of the Ia allele (p) = 0.2607 and the frequency of the Ib allele (q) = 0.134.

Who is universal acceptor blood?

O– group neither has antigen for blood group nor it has the antigen for Rh factor, hence O– is a universal donor. AB+ blood is a universal acceptor since it has no antibodies to A, B or Rh in its blood and may receive red blood cells from a donor of any form of blood.

What are the 4 blood types and their genotypes?

ABO Blood Types

• Type A: The genotype is either AA or AO. The antigens on the blood cell are A and the antibodies in the blood plasma are B.
• Type B: The genotype is either BB or BO. The antigens on the blood cell are B and the antibodies in the blood plasma are A.
• Type AB: The genotype is AB.
• Type O: The genotype is OO.

Which blood is universal acceptor?

AB+ is the blood group which is a universal acceptor since it has both kinds of antigens, which are Antigen A and Antigen B. People having a blood group of AB+ can accept blood from any person of any blood group.

How do you know if you’re an AA or AO?

If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.

What is OO genotype?

People who are type O have OO genotypes. In other words, they inherited a recessive O allele from both parents. The A and B alleles are codominant. Therefore, if an A is inherited from one parent and a B from the other, the phenotype will be AB.

What is the frequency of Abo in the US?

Frequency of ABO blood group antigens A:43% Caucasians, 27% Blacks, 28% Asians B:9% Caucasians, 20% Blacks, 27% Asians A1:34% Caucasians, 19% Blacks, 27% Asians Note: Does not include AB blood groups (1). Frequency of ABO phenotypes Blood group O is the most common phenotype in most populations.

What is the ABO allele frequency in rhesus blood group?

Kell, and Rhesus blood group data of more than 600,000 donors were reviewed. Allele frequencies were derived by the maximum-likelihood method. The frequency of D category VI was determined in more than 70,000 Rhesus typings. Results: ABO allele frequencies were: O: 0.640, A: 0.279.

How many different blood types are there in ABO?

A child receives one of the three alleles from each parent, giving rise to six possible genotypes and four possible blood types (phenotypes). Nomenclature Number of ABO blood group antigens: 4

How many ABO antigens are in a human RBC?

Although the ABO blood group antigens are regarded as RBC antigens, they are actually expressed on a wide variety of human tissues and are present on most epithelial and endothelial cells. Each human RBC expresses about 2 million ABO blood group antigens.
