People who have the A antigen normally would not produce the anti-A antibody.
People who are type AB normally produce both anti-A and anti-B antibodies.
The only ABO type blood that normally does not have either A or B antigens is AB.
It was discovered in the 1950's.
It was discovered by Karl Landsteiner
Few people are actually typed for this system because of the difficulty of the procedure and high cost.
A and b
The inheritance of 1 of 3 possible alleles (A, B, or O) from each parent
Genetic inheritance and environmental influences during life
Environmental influences alone
O is recessive
O is dominant over A
B is dominant over A
All of the above
Any of the above
must really have the blood type AB
Is homozygous dominant for the trait
Is heterozygous for the trait
could have several possible genotypes
It is more complex genetically than the ABO system.
It was the first blood type system to be discovered.
There are 45 Rh blood types.
A and c
Rh positive; Rh positive
Rh positive; Rh negative
Rh negative; Rh positive
Rh negative; Rh negative
They are either homozygous dominant (DD) or heterozygous (Dd) for this trait.
They are all homozygous dominant (DD).
They are all homozygous recessive (dd).
They are either homozygous recessive (dd) or heterozygous (Dd) for this trait.
At least 50%
Less than 50%
