In fact, according to the experts, most children who are O-negative have parents who are O-positive.
What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child. Each of their kids has around a 1 in 8 chance of having O negative blood. This is possible because both O and Rh- are something called recessive traits.
For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.

O negative blood group is a type of blood group that does not have any of the major blood group antigens (A, B, or Rh).
