it depends on the mother blood type. in genetic there is such terms called autosomal recessive and autosomal dominant. there is several blood types : AB, A,B and O. each… kind of blood type has rhesus positive or negative, depends on the inheritance. when there is A,B,AB and all of them are rheus positive they are autosomal possitive. there is a tabel that will show it clearly: (parents)AB +B=(offsprings) AB, B (p)AB +AB= (O) A,AB,B (P)A+A= (O) A (P)A+AB= (O) A,AB (P)A +O =(O)A (P)O+O=(O) (P)AB+O=(O)A,B So, finally to your question : it is possible that father with AB will have a childreb=n that is B , but it depends on the mother blood type and also depends on the positive and negative RH. (MORE)1 person found this useful hope it help ya

If both of Mr Jone's parents were AB, then the possible blood types of their children would be AA, AB, and BB. This means that Mr Jones has a pure type B blood. Using the Punnett square to determine the possible blood type of their children
    | B   |  B
A | AB | AB
B | BB | BB

The possible blood types of their children are AB and BB. So there is 0 probability that they will have a child of blood type A.
