a person with AB blood group exhibits a genetic principle called co-dominance
A person with phenotype AB blood must have genotype AB blood. Meaning that the person has inherited both A and B alleles.
they have AB blood because it has antigens
A person with A negative blood can donate blood to a person with A negative blood and a person with AB negative blood.
no because AB only can donate to AB.
Blood group AB can only donate red blood cells to other AB individuals. Since donated blood is separated into different components, your blood and plasma may be donated to different individuals. While AB red blood cells are only compatible with other AB individuals, AB plasma is the universal plasma for donation.
If a person has AB type blood then they can receive any type of blood. A extra factor you have to take into account is whether they are AB positive or AB negative. An AB+ person can take any blood while an AB- person can take any blood as long as its negative. For a chart showing the blood type compatibility see http://en.wikipedia.org/wiki/Blood_types#Red_blood_cell_compatibility
The AB blood type is known as the universal recipient. Therefore, the groups that a person with this blood type can give blood to are limited. If your blood is AB+, then you can only give to others with AB+ blood. If your blood is AB-, then you can give to people with both AB+ or AB- blood.
If a person is blood type A, then they can be either AA or AO. The person with AB, has to be AB. So the possible combinations are AA, AB, AO, or BO. So, their offspring could be type A, type B, or type AB, but could not be type O.
A person with type A blood can donate blood to a person with type A or type AB. A person with type B blood can donate blood to a person with type B or type AB. A person with type AB blood can donate blood to a person with type AB only. A person with type O blood can donate to anyone. A person with type A blood can receive blood from a person with type A or type O. A person with type B blood can receive blood from a person with type B or type O. A person with type AB blood can receive blood from anyone. A person with type O blood can receive blood from a person with type O. hope this helps, #JC# http://www.fi.edu/learn/heart/blood/types.html
because there is a trace of B blood in AB blood they can receive B blood>
Yes, you can
A person with type A blood can donate blood to a person with type A or type AB.
