What is the genotype of AB?

Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

What are the alleles for AB blood type?

Under normal inheritance patterns, the person with type AB blood will have one A allele and one B allele. They will give either allele to their children, who will receive a copy of the O blood type gene from the second parent. These children will all have either type A or type B blood.

Is blood type AB a phenotype?

The possible human phenotypes for blood group are type A, type B, type AB, and type O.

Which blood type follows Codominance rule?

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

What does blood type AB mean?

Group AB: The red blood cells have both A and B antigens, but the plasma does not contain anti-A or anti-B antibodies. Individuals with type AB can receive any ABO blood type. Group O: The plasma contains both anti-A and anti-B antibodies, but the surface of the red blood cells does not contain any A or B antigens.

What is Bo blood type?

BO = B blood type. OO = O blood type. AB = AB blood type.

What type of people have AB blood?

The AB blood group is believed to be the newest blood type. The AB blood group is the result of the intermingling between Caucasian (commonly group A) and Mongolian (commonly group B) people. For these reasons, the AB blood group is found in low percentages throughout the European population,…

How many people have AB blood?

AB Positive. Only 1 in every 29 people of the population have AB+ blood. AB+ is the universal recipient and the universal plasma donor, making it a very important blood type.

What are the possible genotypes for blood type?

If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative.

How rare is AB negative blood?

AB negative is the rarest blood type in the U.S. Only 0.6 percent of Americans have this type of blood, according to the Stanford Blood Center in Stanford, California.
