If one parent has type B blood and the other type O blood what percentage of the child's blood will be B, O, A?

Answer:

If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.

Explanation:

Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.

Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.

Blood type A contains antigen A and its genotype can be A|A or A|O.
Blood type B contains the B antigen, whose genotype can be B|B or B|O.
Blood type AB contains both antigens and a single A|B genotypic expression.
Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.

Scenario 1: Parent with genotype B|B.

In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.

B|B X O|O

Alleles B B

O B|O B|O

100% of the offspring would be of blood type B.

Scenario 2: Parent with genotype B|O.

In this case, 50% of the offspring will have blood type O and 50% B.

B|O X O|O

Alleles B O

O B|O O|O

In no scenario would offspring of blood type A be possible.
