What blood type may be the son of a male with blood type B and a woman with blood type A

Hello, according to the law of heredity of medical ABO blood group, the blood type of the next generation (both male and female) may be A, B, AB or O, this is the conclusion, if you want to know more, please see the medical analysis below.

The control of ABO blood group is controlled by a pair of genes, the genes are represented as A, B, and I, and the genes exist in pairs, for example, when a person's blood group gene is AA, AI, this person is blood group A, if BB, Bi, it is blood type B, AB gene is blood type AB, and II is blood type O.

According to Mendel's law of gene segregation, the next generation of blood group genes can be AA, AI, BB, BI, AB, II, so the next generation of blood types can be divided into four types: A, B, AB, and O.

Hope, and wish the landlord a happy new year! o( oHa!

ps: I am very pleased to see your question, after all, the landlord wants to explain the problem with scientific methods, and some people's questions are very ignorant, saying his birthday and constellation, asking blood type, I really feel a failure in China's education!

Damn, don't talk nonsense. a, b, ab, o are all possible. There are many examples around me.

Learn about the ABO blood group system.

I don't understand, but I feel, b, a, ab, it's all possible, whatever blood you have in your elders, you will have whatever blood. It may be possible to do so.

Male A and female B will have a child in one of the four blood types A, B, AB, and O.

Blood type is determined by the combination of three genetic factors such as A, B, and O, and most of them can be judged according to the blood type of the parents. The most common is the ABO blood group system, which is divided into four types: A, B, AB, and O; followed by the Rh blood group system, which is divided into Rh-positive and Rh-negative; In addition, there are extremely rare state Zen blood group systems such as MNS and P.

Extended pants attack data:

Human cells have a total of 23 pairs of chromosomes, each of which is made up of two single chromosomes, one from the father and the other from the mother. The main component of chromosomes is the DNA that determines the inherited traits and functions, that is, each segment has unique genetic traits and functions, and these segments are called genes.

A small fragment of DNA at the same location on two single chromosomes in a pair of chromosomes, the gene locus of the ABO blood group system is on the 9th pair of chromosomes, and the ABO blood group is controlled by three genes, AA, B, and O, which can be combined into six pairs of alleles AA, AO, BB, BO, AB, OO. ABO blood group has six pairs of allele combinations, so there are six genetic formulas, such as the above two cases of the genetic formula AA and AO respectively.

In the ABO blood group system, genes A and B are dominant, while gene O is recessive. If the child is born with a chromosome from both parents carrying the O gene, the allele combination of the child's chromosome is OO, the genetic formula is OO, and the expression is O, that is, the child's blood type is type O.
