What blood type will a baby be if both parents are O negative?
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.
Can two O Negative parents make an O positive child?
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….ABO Blood Type Calculator.

What if both parents are type O?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.
Can you only be O blood type if both parents are O?
Suffice it to say that A, B and AB are dominant over O, so children will be type O only if they inherit O-type genes from both parents. As a result, their child could wind up as type O if the other parent passes them an O-type gene, too. That last fact explains how O-positive parents can have O-negative kids.
What are the chances of having a child with O Negative?
In that case it is a 25\% probability that the child will be O-negative, as they would have to inherit the d (lack of rH) from both parents. Since both parents are type O, the child will be of blood group O, as there is no other ABO gene to be passsed on.
What blood type would a child of two O Negative parents be?
The child of those parents could legitimately have any blood type. If both parents are O negative, does that mean the children will be O negative? Assuming the blood typing was done correctly ( not a 4th grade science project) and recorded accurately, then the child of two parents, both Type O negative, would usually be type O negative.
What does it mean to couple with O Negative blood?
When you say “couple with O negative blood” I am assuming you mean that both the mother and father have this blood type. During a pregnancy, the baby growing inside Mom has a blood type that is determined partly by the genes that she contributed through her egg, and partly by the genes that Dad contributed with the sperm.
How does a person become Type O if they have children?
So, for a person to be type O both of their alleles have to match, and all of their children will get an O gene from them. If two people who are type O have children, all of the children will also be type O because those are the only alleles involved.
