I want to know if the father with blood type Orh +, mother Arh- can be the father of the daughter and blood type ABrh-. Thank you for your answer.
Whenestablishing paternity , research based on the analysis of the so-called polymorphic markers, which is best done in a certified forensic facility. Prediction tables on the Internet should not be used in determining paternity, as there are exceptions to each rule. In the described case, for example, the occurrence of a de novo mutation in the child cannot be ruled out a priori, which changes the enzymatic activity of the protein in such a way that in the serological test its blood group is recognized as AB.
