Anonymous users2024-02-11Blood type is determined by a combination of three genes: a, b, i.
There are two possibilities for blood type A: AA gene and AI gene.
There are two possibilities for blood type B: BB gene and BI gene.
One possibility of AB blood type: AB gene.
Blood type O is also a possibility: the II gene.
The child's two blood group genes are one for the father and one for the mother.
So the answer to the question asked is:
A blood type (including the AI gene), and B blood type (including the BI gene) or O blood group (including the II gene) can give birth to a child with blood type O. Only AB type is not allowed.
I am an undergraduate medical student, and the answer is for reference only. The original meaning of blood type is determined by antibodies and antigens, but its internal logical relationship is a bit complicated, and there are many combinations and arrangements.

Blood type O has the greatest chance.

Anonymous users2024-02-08Blood type O is dominant, and if a pair of chromosomes have blood type O genes, then the child will certainly not be O
type, no matter what blood type the man is. If only one chromosome is present, then after marrying a man with blood type O, the probability of having a child with blood type O is the highest (75%), regardless of the sex of the child.

Very authoritative, give points,!

Anonymous users2024-02-06A man and a woman with type O blood can give birth to a child with type A or O, according to the genetic table of blood type, the specific rules are as follows:
1. O and O: The blood type and O that the child will appear
2. A and O: The blood type, A, and O that the child will have
3. A and A: The blood type, A, and O that the child will have
4. A and B, the blood type that the child will appear, A, B, Ab, O5, A and AB: The blood type that the child will appear, A, B, AB

Anonymous users2024-02-05According to the law of human blood group heredity: parents are O+A blood type, children may have blood type O and A blood type, and impossible blood types are B and AB blood types.
Blood group is a classification based on differences in antigens of the same family on the surface of human red blood cells. Because human red blood cells contain different agglutinogens, the blood is divided into several types, so it is called blood type.
Blood group heredity is the theoretical basis for clinical blood transfusion and organ transplant matching. Blood type as a genetic trait is rarely influenced by the environment, so it is an excellent genetic marker for paternity testing, disease association analysis, and human evolutionary studies.
Type B is best matched with Type B, and Type O is optional. >>>More
