Question

which blood group will expect on crossing to parents with O blood groups​

Answer 1

Answer:

O Blood group.

Explanation:

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.
