I, the father, have the blood type ABRh +, wife BRh +, and our daughter BRh-. Is it possible that our child has inherited a negative blood group?
This situation is possible because the inheritance of blood types follows Mendel's laws. The Rh factor is inherited predominantly and the ABO blood groups are inherited codominantly. Rh + parents may have an Rh - child.
The mechanisms underlying blood group inheritance have been discussed in my previous answers to internet users' questions.
