Yes.
Because an A blood type person could be an AO, and have one allele for A and one for O.
If both parents give their O allele to the child, the child will be of the O blood type from A blood type parents.
Similiarly, there are two alleles for antibodies, and the + parents could be +- or ++. If they are both +-, they could both give the - allelle to the child, resulting in an O- child.
It would be rare, but possible.
(Remember in both these cases, the A and + alleles are considered dominant.)

yeah !!!!!!!! it's possible b'coz we know dat any blood group has 2 alleles likewise "A" blood can have 2 possible genotype I^a I^a or I^a I^o. both of these genotype leads to "A" blood group. if both the parents are hetrozygous 4 "A" bloodgroup they can have baby of "O" blood group. + & - is only 4 Rh bloodtype they r not at all related in blood group determination of offsprings. if you take cross of parents with such type of bloodgroup u will get I^a I^o X I^a I^o the ratio of offspring is I^a I^a: I^a I^o: I^o I^o= 1:2:1. hence there is possibility of baby of "O" bloodgroup 4m these parents.

Yes, so person A is A/O;+/- and person B and be A/O;-/-
