Since negative blood types are recessive, both parents can have a recessive negative gene. This means that yes, two people with positive blood types can have a child with a negative blood type.

∙ 12y agoYes! My Mom is A+ and my dad is O+. Out of 4 siblings, 2 of us are A- and 2 are O-. I was told it wasn't possible, but testing was done, and its true.
I have to agree with this as well. My mothe is A+ amd my father is O+ and I am A-! I started wondering, what the heck. Am I gonna be on Maury looking for my real daddy but it appears that is is quite rare but happens.

The most obvious reason this has happened would be that your wife has cheated on you, but if it makes you feel any better then take the easy way out..... You're wife is having the next Jesus..

∙ 12y agostrangely enough, I do think they can; reason being after all the X and Y chromosomes line up, there can possibly be a negative result slipped in from grandparents or great-grandparents.

∙ 12y agoThere can be serious problems if the mother has a negative blood type and the father has a positive blood type, but there are medications to help prevent blood-related complications.

Can a child have a negative blood types if the parents are both a positive?
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
Can someone with B negative blood type have a child with someone with b posititve blood type?
Absolutely - all blood types can have children together. The only problem relating to these blood types for pregnancy would be if the mother is negative and her first child was positive. Then there may be a problem if her second child is also positive.
What happens when blood group of father is O positive and mother is B negative of an unborn child?
The child may have either O or B blood type, assuming that the mother has a recessive allele for O blood type. A child of parents with both positive and negative Rh factor may have either. So, the child could have O positive, O negative, B positive, or B negative blood types.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
Can parents who have B negative and O positive blood types have a child with B positive blood?
Yes. They can have B+, B-, O+, and O-.
Can two O positive blood types have a child with A negative blood?
Yes. The geneotype for both parents must be AO+- for the child to be OO--
Can a man with type B negative blood father a child with A positive blood if the mother has O negative?
No because it's not possible for those to blood types to creat O negative
How can doctors determine positive or negative blood types.?
Doctors can determine positive or negative blood types by administering a test. The difference between positive and negative types is the presence of the RH factor. Positive blood types indicate the presence of the RH factor while negative blood types do not have this factor.
