Question

is the child's blood group decided by parents??? with reason​

Answer 1

While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!

But two O parents, for example, will pretty much always have O kids. They will match both parents.

As you can see, sometimes kids’ blood types match and sometimes they don’t. There are certain genetics “rules” that allowed me to get to this answer, which I break down for you below. But like any good rules, there are exceptions.

Answer 2

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter.....
