The adopted child will have a type O blood group despite the fact that the mother has type O, the father will pass on an A or a B allele to the children. These are dominant alleles.

What are blood groups?

Blood groups are divided into four categories: A, B, AB, and O. The presence or absence of two antigens on the surface of red blood cells determines each one.

A and B are the names of these antigens. Type A blood is defined by the presence of antigen A on red blood cells. Type B blood is defined by the presence of antigen B on red blood cells. You have type AB blood if both antigens (A and B) are present on your red blood cells.

And if neither antigen (A or B) is present on your red blood cells, you have type O blood.

Thus, we can conclude that the adopted child blood group will be O.
