On saturday in NMC labor room a child was deleivered with blood group A-. His mother group was A+ and his father's B-. All doctors stunned hows it is possible . the child blood group was 3 times checked and everytime it comes out to be A-. the doctors are not ready to accept it. Now u people prove is it posiible or this child does not belong to his so called parents. prove with crosses. #shocked

that is definetly possible as both rhesus and clood type are transmittted in a Mandelian fashion

Fathers genotype BO Rhesus status --(Both alleles of rheusus must be negative inorder to have a negative blood group)
mom AO Rh status +(But genotype must be + and -)

Thus child can be any negative.

If fathers genotype AO
Mothers Genotype BO

Then 25 % chance of child being OO thus o blood group rest of the possibiklities woulf be AB AO and BO ,thus 25 % chance of the child being either O ,AB ,A or B.
