This means if you get the "A" (or B) gene from one parent, and the "O" gene from another parent, your phenotype (in this case your actual blood group) will be A. The O gene doesn't produce a blood group at all, A and B genes do.
No.
A and B are co-dominant. they are both dominant to recessive O.
So you get four blood groups;
A, B , AB and O
explain co-dominance selecting the example of ABO blood group system
The progeny could have any of the 4 blood groups, viz., A, B, AB and O. (positive only) The ABO blood typing system is an example of codominance. In codominance, both the alleles are expressed.
It isn't really a condition but a term used for codominance. ABO blood type is an example.
The ABO blood group system was discovered in 1900 by Karl Landsteiner. The AB blood group was discovered by Von Decastellor and Sturli in 1902.
A person with blood type AB cannot give blood to anyone but can receive blood from anyone
In the ABO blood system, type O positive blood is common, about 36% of the population. 90% of the population is Kell negative. So no, it is not rare.
ABO blood types are controlled by codominance and multiple alleles.

The ABO blood grouping system was established by Karl Landsteiner in 1900. He was awarded the Nobel prize in Physiology or Medicine in 1930.

The ABO blood group system was discovered in 1900 by Karl Landsteiner. The AB blood group was discovered by Von Decastellor and Sturli in 1902.
blood type
In the ABO system, it is O blood type that contains no surface antigens.
abo blood group system was discovered in 1901 and rh was discovered in 1940.
The ABO blood was discovered by Karl Landsteiner in 1900.He explained that agglutination occur due to the presence of antigen on red blood cells and the corresponding antibodies in the serum.
