How do siblings have different blood types?
Blood types are inherited and represent genetic markers from both parents, so the answer to this question depends on the blood types of the parents. Each biological parent donates one of their two ABO alleles to their child. If both parents are Type A, for example, then their children must also all be Type A.
Is the blood type of siblings the same?
So depending on which genes the parents have, siblings can easily have different blood types. There are some restrictions. If one parent is AB, then the children have to be either, A, B, or AB. If one parent is O, then the children can’t be AB.
Are siblings expected to be of same blood group?
As far as this discussion is concerned, the answer is no. Siblings may not have the same blood group. This results in various circumstances such as if both the parents are of type A (for instance), the the offspring will have a type of either A or AB. So, one of the siblings may have a blood type of A and the other with type AB. I hope you got it.
Do brothers and sisters have the same blood type?
Brothers and sisters do not necessarily have the same blood type. First, there are four blood types: A, B, AB, and O. But, each of these blood types has two elements, just as AB does. Blood type A is either AA or AO.
Are all children of same parents the same blood type?
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.
Why do I have different blood type than my parents?
BEST ANSWER Yes, there are some limits of what blood type your baby could be. According to www.keepkidshealthy.com/newborn/babys_blood_type.html, the parents’ blood types limit what the child’s can be, but the child does not necessarily inherit one or the other type.
