Anonymous users2024-02-07Blood type and genetics.
In general, blood type is constant throughout life.
Human blood types are usually divided into four types: A, B, O, and AB. Blood type is inherited with the help of chromosomes in cells. There are a total of 23 pairs of chromosomes in a human cell, and each pair of chromosomes is made up of two single chromosomes, one from the father and the other from the mother.
The main component of chromosomes is deoxyribonucleic acid, which determines genetic traits and functions, which can be divided into many small segments, each of which has specific genetic traits and functions, and these small segments are called genes. A small fragment of DNA in the same position on two single chromosomes in a pair of chromosomes, called an allele.
The locus of the ABO blood group system is on chromosome 9. Human ABO blood group is controlled by three genes: A, B, and O, but there are only two ABO system genes on the 9th pair of chromosomes in each human cell, namely a pair of alleles in AO, AA, BO, BB, AB, and OO, in which A and B genes are dominant genes and O genes are recessive genes. The genetic pattern of the ABO blood group system is shown in the following table:

Anonymous users2024-01-281. From the father is type A, the eldest daughter is type A, and the mother is type B, it can be concluded that the mother's blood type genotype must only be BI, and the eldest daughter's blood type genotype is AI;
1. If the father's blood type genotype is AA, the probability that the youngest daughter's blood type genotype is AB is 50%, and the probability of AI is 50%, that is, the probability that the youngest daughter's blood type is AB is 50%, and the probability of blood type A is 50%.
2. If the father's blood type genotype is AI, the probability that the youngest daughter's blood type genotype is AB, AI, BI, and II is 25%, that is, the probability that the youngest daughter's blood type is AB, A, B, and O is 25%.
In summary, the probability that the youngest daughter's blood type is AB or A is the same as the probability of B and O.
2. 1. If the father's blood type genotype is AA, the probability that the youngest daughter's blood type genotype is AB is 50%, and the probability of AA is 50%, that is, the probability that the youngest daughter's blood type is AB is 50%, and the probability of blood calling the chaotic return type A is 50%.
2. If the father's blood type genotype is AI, the probability that the youngest daughter's blood type genotype is AA, AI, AB, and BI is 25%, that is, the probability that the youngest daughter's blood type is A is 50%, and the probability of AB and B is 25%.
In summary, the probability that the youngest daughter's blood type is A is 50%, the probability of being AB is, and the probability of being B is.

Anonymous users2024-01-271 The youngest daughter can be any of the one of the A o b Ab types of the Eggplant Odds of carrying the same.
2 The mother is type AB and the father can give birth to a child with blood type A when the father is A, B, or O blood type, and the blood type of the youngest daughter can be type A, B, and AB The probability is the same.

Anonymous users2024-01-26It can be type A, type B, type AB, type O, if the daughter is blood type A, then the father's genotype is IAIA or IAI, and the mother's can only be IBI, so the probability of the younger daughter's scum finch blood type is 1 liquid beam skin 8, the probability of blood type A is 3 8, the probability of blood type B is 1 8, and the probability of blood type AB is 3 8

Anonymous users2024-01-25I like raw socks and physics, so I'll give you an answer. By blood type, blood type refers to phenotype, just like our hair color. Both black and yellow are phenotypes, but what controls their phenotype is a combination of genes and environment, to be specific:
An identical twin. The genotype is all white skin color, but one does not leave the house at home, and the other basks in the sun every day on the beach, which one do you say will be dark? You're asking about blood type, which is also an environmental influence, but the chance is almost zero.
There are also mutations in genes, which are also almost zero. The first question you ask Brother Hao Oak is that the younger daughter's blood type is not affected by the older daughter. The youngest daughter's blood type may be AB type, type A, type B, type O, and the probability is 1 in 4.
The second question you ask is that the youngest daughter may have a 3-in-1 probability of being type A, AB or B. This answer is a normal probability.

Anonymous users2024-01-24This question is not absolute, as long as there is a 1% possibility, relative to the individual, it is 100% so what you said Don't guess Wu Yan's answer is very difficult, and you are not polite to say that it does not exist.
Guess the outcome is of course a variety of possibilities, but unfortunately you don't have to guess.
There is no way to cite this.
1. Blood type A.
Blood type A is one of the common blood types and refers to the presence of A antigen in the blood. A blood group that belongs to the ABO blood group system. Type A is further divided into two subtypes: A1 and A2. >>>More
China's current blood donation law stipulates that blood collected at non-blood stations is not allowed to be transfused except for autologous blood. For that reason, the hospital will definitely reject you, otherwise they will be breaking the law. One of the main reasons for this article is the fear of blood-borne diseases, and of course the fear that people will use it to sell blood. >>>More
The blood type that is prone to longevity is type O blood, and studies have found that people with blood type O have the longest average life expectancy, which can basically reach 87 years old. However, although blood type has an impact on a person's physical health, in many cases, people's lifestyle habits ultimately determine whether humans can live a long and healthy life.
A person's blood type is innate, and it doesn't change for life. However, under certain circumstances, a person's blood type can change. >>>More
In general, blood types are mostly formed at birth and remain unchanged throughout life. In some special cases, blood type can be changed. >>>More
