What are the 6 genotypes for the four blood types?

There are three alleles involved, A, B, and O, and six possible genotypes: AA, BB, OO, AB, AO, and BO. The various genotypes result in four different phenotypes or blood types: A, B, O, and AB.

What are the 4 possible genotypes for blood?

The different possible genotypes are AA, AO, BB, BO, AB, and OO.

What are all the possible genotypes for type A blood?

Genotypes

Blood Type Genotype
Blood Type A Genotypes AA or AO
Blood Type B Genotypes BB or BO
Blood Type AB Genotype AB
Blood Type O Genotype OO

What is the basis of ABO blood types?

ABO grouping is a test performed to determine an individual’s blood type. It is based on the premise that individuals have antigens on their red blood cells (RBCs) that correspond to the four main blood groups: A, B, O, and AB.

What phenotypes and genotypes are possible for ABO blood types?

Table 4-5. Correlation of ABO phenotypes and genotypes.

Phenotype Possible Genotype
A AA or AO
B BB or BO
AB AB
O OO

What is Timmy’s maternal grandfather’s genotype?

What is Timmy’s maternal grandfather’s genotype? Grandpa is homozygous dominant (FF) for freckle trait.

Does blood type follow Punnett Square?

When the blood types of both parents are known, you can find the possible blood types of a baby. First, you have to determine which genes each parent could pass down, then you can draw a Punnett square, and finally calculate the percent chance of each blood type.

What is the best blood genotype?

Health Tips

  • Types of Genotype. The genotypes in humans are AA, AS, AC, SS. They refer to the hemoglobin gene constituents on the red blood cells.
  • Compatible genotypes for marriage are: AA marries an AA. That’s the best compatible.
  • Solution. The only thing that can change the genotype is the bone marrow transplant (BMT).

What is the genotype for blood group O+?

Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

How many genotypes are there for ABO blood type?

There are six possible genotypes (genetic makeup of inherited alleles) and four phenotypes (expressed physical trait) for human ABO blood types. The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotype is homozygous recessive and the blood type is O.

Can a parent have a negative blood type?

If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types. Rh Positive (Rh+) and Negative (Rh-) Blood Types

Which is an example of a homozygous recessive blood type?

When both inherited alleles are O, the genotpye is homozygous recessive and the blood type is O. When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB. AB blood type is an example of co-dominance since both traits are expressed equally.

How can blood type be used to determine paternity?

The ABO blood type charts below can be used to predict the possibilities of paternity. 1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or 2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart).
