Question

Can a man with blood group A have children with blood group O . Support your answer with proper explanation ?

Answer 1

Answer:

yes because it is not a rule to have a same blood group of their children and parents

Answer 2

Answer:

The child can only pass on an A gene to his offspring. If one parent contributes and A gene and the other contributes an O gene, the child will have A blood type, but, like his parents, he'll also have both A and O genes that he may pass along to his children.
