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.
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.
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).

It isn't really a condition but a term used for codominance. ABO blood type is an example.
Codominance is a genetic phenomenon where both alleles in a heterozygous genotype are fully expressed, resulting in a phenotype that displays characteristics of both alleles equally. In the context of blood groups, the ABO blood group system illustrates codominance with alleles A and B; individuals with genotype AB express both A and B antigens on their red blood cells. This results in the AB blood type, which is distinct from the other types (A, B, and O) that express only one type of antigen or none at all. Thus, codominance explains the coexistence and expression of multiple traits in certain genetic combinations.
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.

I disagree with the nurse's statement that a person can't have the blood type ABO. The ABO blood group system consists of four main blood types: A, B, AB, and O, which are determined by the presence or absence of specific antigens on the surface of red blood cells. Therefore, individuals can indeed have one of these four blood types, which are all part of the ABO system.
