Yes.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
The father's blood type could be either A positive or A negative. The children inherited the A antigen from the father, resulting in their blood type as A negative. The Rh factor (positive or negative) is inherited separately, so the father could be either positive or negative.
Look at the Grandparents.
An AB+ and B- couple can't have a child with blood type O. They can have children with blood types A, B, or AB, and can have children with Rh negative or Rh positive blood.
