Can parents have type O children with type O What blood type does it take to give birth to what kind

If both parents have type AB, it is basically impossible to have a child with type O blood, but it is possible that both parents have recessive I chromosomes, as the person said above, but the probability is very low.

The genes for blood are a, b, and iAA, AI is type A, BB, BI is type B, II is type O, oh, and AB blood type.

Parents = offspring.

o+o=o o+a=o,a

o+b=o,b o+ab=a,b

a+a=o,a a+b=o,a,b,ab

b+b=o,b a+ab =a,b,ab

b+ab=a,b,ab ab+ab=a,b,ab

It can't be O-shaped. There is a genetic law of what blood type gives birth to what blood type of child.

Both parents have AB blood type, that is, the blood group dissociates into A or B Two groups of A or B free combination, it will form AA AB BB This is the so-called blood type A, blood type AB, blood type B.

However, there are not only two manifestations of blood type A or B, and AI and BI can also be expressed as blood type A and blood type B.

There is only one manifestation of AB blood and O blood, and that is AB and II I don't know if you understand!? This has something to do with genetics! Hehe.

It is also possible that if the parents have a recessive type O, the child may have type O, and if the parents have the same blood type, the child's blood type will be the same as the parents, and the children born to type A and type B have type A, b ab, type three, type AB and type O, and type A b ab o.

It is also possible that in the case of variation.

It won't be O, and the maximum possible is ab There is a chance that it will be A or B

It can't be o, or a, or bAbsolutely.

1. Children born to parents of AB blood type and blood type O can be blood type A or blood type B, both are possible. But it certainly won't be blood type O or AB blood. Blood types include ABO blood group and RH blood group, and the so-called trillion blood group actually refers to the type of antigen on the surface of red blood cells.

If you have type A antigen on your red blood cells, then you are type A, if your red blood cell surface antigen is type B antigen, if you have both type A antigen and type B antigen, then you are type AB, if you have none, you are type O.

2. The child's blood type is controlled by the parents of the biracial party, and the child's chromosomes come from the mother and the father of the child, so the combination of the mother of type AB and the father of type O or the combination of the father of type AB and the mother of type O can only give birth to type A or type B treasures. In the same way, parents with blood type A and blood type O can only give birth to type A and O babies. Parents with blood type B and blood type O can only give birth to babies with type B and O.

And if it is currently type O blood, the child born in the future may have the possibility of hemolysis, it is best to go to the hospital to check the ABO blood type and actively prevent neonatal hemolysis.

1. There are two possibilities for children born with blood type O and blood type B, one is blood type O and the other is blood type B, which cannot be blood type A or blood type AB.

2. Because people with blood type O have neither A antigen nor B antigen on the red blood cell membrane, its expression form is two O antigens. Human red blood cells with blood type B contain B antigen on their membranes, and it is expressed in the form of two or one B and one O. So people with blood type O can only provide O, people with blood type B may provide O, and they may also provide B, if both O are together, the offspring will be blood type O; If one O and one B are together, the offspring is blood type B.

Therefore, the offspring of people with blood type O and blood type B can only be blood type O or blood type B, and it cannot be blood type A or AB blood.
