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.
Codominance is when both alleles are expressed in the offspring. This results in a phenotype where traits from both alleles are visibly present. An example of codominance is the ABO blood group system in humans.
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.
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.
Codominance occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles, such as in blood type AB. Multiple alleles refer to the existence of more than two alternative forms of a gene within a population, allowing for a variety of genotypes and phenotypes, like the ABO blood group system where three alleles (A, B, O) determine blood type. While codominance describes the expression of alleles, multiple alleles describe the variety of alleles available for a trait.

The ABO blood types are controlled by specific alleles of the ABO gene. These alleles determine the presence or absence of antigens on the surface of red blood cells, which in turn determines an individual's blood type (A, B, AB, or O).

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

ABO is a classification system for human blood types based on the presence or absence of antigens on red blood cells. There are four main blood types in the ABO system: A, B, AB, and O. These blood types are important for blood transfusions and organ transplants.

Testing for Rh antigens and antibodies is done to determine the presence of the Rh factor in the blood, which is a separate system from the ABO blood group system. Rh testing is important for determining compatibility in blood transfusions and during pregnancy. ABO testing, on the other hand, evaluates the presence of A, B, AB, or O antigens on red blood cells to determine blood type.
