All Possible Blood Type Genotypes

February 18, 2021

Similarly someone who is blood type b could have a genotype of either bb or bo. O blood type.

While blood types a and b are codominant to each other they are both dominant to the o allele.

All possible blood type genotypes. Here a punnett square with each possibilities. The total number of possible crosses is exactly 21. Genotype and phenotype chart for human blood types predicting blood type.

A blood type. A b o and ab. The a and b alleles are dominant to the o allele.

A person with blood type a could have the genotype aa or ao. For example two o blood type parents can produce a child with only o blood type. I highlighted the possible parent genotypes.

Parent 1 and 2 have each 5 possible genotypes oo ao bb bo and ab. There are four possible blood types and six possible genotypes. It is not possible to determine the exact genotype from a blood test result of either type a or type b.

B blood type. The table below lists all of the possible genotypes and resulting phenotypes for blood types in humans. As a result you can have blood type a or b either by inheriting two copies of the a or b allele or by inheriting one copy of the a or b allele and one copy of the o allele.

A person with blood type b could have the genotype bb or bo. Two parents with a blood type can produce. This is explained in the following chart showing the different the genotypes that make up the blood types.

Genotype dna blood type. There are six possible genotypes genetic makeup of inherited alleles and four phenotypes expressed physical trait for human abo blood types. Individuals have blood type b if their.

Individuals have blood type a if their genotypes are aa or ao. If someone has blood type a they must have at least one copy of the a allele but they could have two copies. When both inherited alleles are o the genotype is homozygous recessive and the blood type is o.

The various genotypes result in four different phenotypes or blood types. Their genotype is either aa or ao.
