What is called blood group matching logic, logic circuit design blood group matching with NAND gates

Blood type is determined by genes located on chromosomes. Human cells contain 23 pairs of chromosomes, half of which come from the father and the other half from the mother, and these chromosomes carry thousands of genes from both parents that are passed down from generation to generation.

ABO blood group is determined by three blood group genes, A, B, and O, and the blood group genes are located on the 9th pair of chromosomes. Since A and B are dominant genes and O are recessive genes, as long as one of the 9th pair of chromosomes has a gene A, regardless of whether the corresponding locus of the other chromosome is a and O genes, it will be characterized by blood type A. For type O blood, it must be the 9th pair, and both chromosomes have the same O gene.

If chromosome 9 has a gene A and a gene on the other chromosome, it is blood type AB. According to this reasoning, if the man of a couple has blood type A and the woman has blood type O, then their children's blood group inheritance may have two combinations, that is, 3 4 people have blood type A and the other half have blood type O. Therefore, the blood type of the child can be different from that of the mother or the father.

The inheritance of the three antigens of ABO is controlled by three alleles, and the blood group gene is the complex allele, and there are three blood group genes at the relative locus, namely A, B or O, so the sum of genes at the relative locus is AA, BB, OO, AB, AO or BO Six combinations are called genetic formulas. A or B is a dominant gene, O is a recessive gene, and the phenotypes corresponding to the above genetic formulas are A, B, O, AB, A, and B, which are actually four types: A, B, O, and AB.

Logic circuit design blood group matching with NAND gate 7400 and 7420 I will give you a detailed answer.

It's Rh-positive type A, which is normal, and very few people will have Rh-negative blood.

Blood type O+ means that the blood type is O blood type and the Rh blood group is positive.

The rhesus blood group system, which means rhesus monkey blood group system, is a blood group system of humans, which is divided into negative and positive. When a person has a D blood group substance (antigen) present on their red blood cells, it is called Rh positive, which is denoted by Rh (+); Rh negative is considered Rh negative when D antigen is absent and is denoted by Rh(-).

Most people are positive, and the RH system is probably the most complex of red blood cell blood groups, second only to the ABO system in importance. The proportion of people with Rh-positive and negative blood types varies according to different races, and the Rh-positive blood type accounts for about 90% of the Han and most ethnic groups in China, and about 90% of individual ethnic minorities, such as the Uyghurs in Xinjiang.

Blood type O positive (+) means that the person's blood type is O blood, and is Rh positive (+) blood type (this is the same as ABO blood type, is another blood type classification, most of the Chinese are Rh positive blood, Rh negative blood is often called panda blood), this is a normal blood type.

Blood groups are generally divided into four types: A, B, AB, and O, and there are more than 10 blood group systems such as RH, MNS, P, etc., which are extremely rare.

Among them, type AB can accept blood transfusion of any blood type, so it is called a universal blood recipient, and type O can be exported to people of any blood type, so it is called a universal blood transfusion, abnormal blood person, in fact, the transportation between different blood types can generally only be delivered in small amounts, not in large quantities. If you want a large amount of blood transfusion, it is better to have the same blood type.

Blood type O is also a type of blood. Because blood types can be divided into type A, type B, type AB and type O. Blood type O is only on the surface of red blood cells and does not contain either A antigen or B antigen.

However, because the plasma contains anti-A and anti-B antibodies, it may cause different degrees of red blood cell hemolysis in the recipient. Therefore, type O blood cannot be arbitrarily transfused to other people. Rh-positive blood with blood type O should not be transfused with any RH-negative blood group, but only a small amount may be transfused into any RH-positive blood group.

However, people with blood type O are not allowed to receive blood transfusions from other blood types, which are prone to hemolytic reactions.

Hello, O+ means that your ABO blood type is O and your RH blood group is positive.

There are generally two types of blood types. That is, ABO blood group and RH blood group, of which the vast majority of RH blood group is positive blood, and only a small part is negative blood.

You are Rh-positive blood type O, abbreviated as O+, generally Han people are Rh-positive blood, sometimes for non-Rh-negative O type O is called O blood. That is, you, like most Han people with blood type O, are rh-positive blood type O.

Blood type o + positivity).

Blood type o - negative).

It means Rh positive or negative. Hemolysis generally occurs only in mothers and babies.

The blood types that have been discovered are divided into four main blood types of red blood cells: A, B, O, and AB.

These blood types are further divided into Rh-positive and Rh-negative.

Rh-positive blood type accounts for about 90% of the Han and most ethnic groups in China, and about 90% of individual ethnic minorities.

In some ethnic groups abroad, about 85% of people with Rh-positive blood type are there, and among those who are Caucasians in Europe and the United States, about 15% are Rh-negative with blood type

Under normal circumstances, blood type A can only accept blood type A, and blood type O can be transfused in special cases, and type AB and B blood are absolutely not. In addition, in addition to the ABO blood group system, it is necessary to check for positive or negative RH.

At present, hospital blood transfusion is to be cross-matched blood, must be fully consistent before blood transfusion, only when emergency type AB can accept other blood types of blood, known as universal blood recipients, type O can be exported to other blood types of people, so it is called universal blood transfusion, transport between different blood types, generally can only be transported in small amounts, not in large quantities. If you want a large amount of blood transfusion, it is better to have the same blood type.

a Because two people want to complement each other, they are too close to each other and are prone to quarrels.

b Because the two personalities are complementary, but one is too perfectionist, and the other is too spontaneous.

ab Because you never understand what he's thinking.

It should be type O, and there is anti-A in type O serum

They are female O blood group and male B blood type, both of which are positive for Rh blood type, which is the same as most people in China.

The following should be the female test results, Ig is the English abbreviation of immunoglobulin (antibody), M and G are the models of globulin, IgM is a recently produced globulin index, which is produced quickly and disappears quickly, and can generally be maintained within a month. IgG is a long-acting globulin that is produced more slowly than IgM and regresses slowly, usually for several years.
