In brief: Using

Using the ABO blood typing system- two parents with type o blood would have a baby with type o blood.
The baby may or maynot be rh positive.

In brief: Because

Because neither parent has a gene for the a blood type (both are o/o in order to have type o blood) the baby could only have type o blood (with the same o/o genes).
Rh positivity can come from three different gene combinations: +/+, +/-, and -/+. The baby would most likely be positive, as well, but has about a 17% chance of being rh negative (-/-).
