Is AB a type of genotype?
Someone with blood type AB must have both the A and B alleles. The genotype must be AB.
How many AB genotypes exist?
The ABO blood group antigens are encoded by one genetic locus, the ABO locus, which has three alternative (allelic) forms—A, B, and O. A child receives one of the three alleles from each parent, giving rise to six possible genotypes and four possible blood types (phenotypes).
Is blood type AB a genotype or phenotype?
If you have an AA or AO genotype, you will have the phenotype of type A blood; if you have a BB or BO genotype, you will have a type B blood phenotype; if you have an AB genotype, you will have a type AB blood phenotype; and if you have an OO genotype, you will have a type O blood phenotype.
What are the 4 blood genotypes?
There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
What does genotype AB mean?
A person with blood type A could have the genotype AA or AO. A person with blood type B could have the genotype BB or BO. A person with blood type AB as the genotype AB. And a person with blood type O has the genotype OO. Blood Type.
What is AB blood type?
Type AB Positive. Less than 4% of the U.S. population have AB positive blood. AB positive blood type is known as the “universal recipient” because AB positive patients can receive red blood cells from all blood types.
Can an AB have an O child?
An AB parent can indeed sometimes have an O child. But it is by no means common. In fact it would be fair to say that it is exceedingly rare. Usually, an AB parent and an A parent can only have children who are Type A or Type B.
Which genotypes can marry?
AC is rare, whereas AS and AC are abnormal. The compatible genotypes for marriage are; AA marries an AA — which is the best compatible, and that way, the couple save their future children the worry about genotype compatibility.
What is special about AB blood?
AB positive blood type is known as the “universal recipient” because AB positive patients can receive red blood cells from all blood types.
How can I know my genotype?
An obvious way to figure out your genotype is to have a genetic test done. Companies like 23andMe can do this pretty inexpensively nowadays. For this to work, though, scientists have to have figured out the genetic difference that leads to a trait.
