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.
a person with AB blood group exhibits a genetic principle called "co-dominance" Explanation there are three genes responsible for the four human blood groups i.e. A, B, O and AB. the genes are Ia, Iband Io. Ia and Ib are dominant genes while Iois a recessive gene. if a person has the genotype IaIa or IaIo he/she will exhibit the blood group "A" similarly a person with genotype IbIb or IbIo will show the blood group "B". But a person with genotype IoIo will show the blood group "O"( IoIo is a homozygousrecessive condition ) since Ia and Ib are dominant genes they express themselves in both homozygous dominant (IaIa and IbIb) condition and heterozygous dominant(IaIo and IbIo) condition. but when the genotype of a person becomes IaIb neither of Ia or Ib genes is able to dominate the other. This is when the principle called "co-dominance" is observed in which both the genes Ia and Ib express themselves to give rise to "AB" blood group.hope i could provide a satisfactory answer ! good luck !!
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
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
Yes, a person with AB- blood can receive O- blood in a transfusion because AB can receive blood from A, B, AB, and O blood types. However, individuals with AB- blood type can only donate to other individuals with AB blood type.
because there is a trace of B blood in AB blood they can receive B blood>
Yes, you can
