What else can I help you with?
Can an a- mom and an O plus father have an ab- child?
No
Can O mom have a child with a father AB?
Yes she can. There are two possible blood-types for the child in this scenario: AO (or A) and BO (or B).
Can an AB mother and an O father have an O child?
No. An AB father does not have an O allele and can only pass on an A or B allele to his child. So the child will either be type A or type B, but not O.
Can a A- mom have a AB- child with a O plus dad?
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
If mother is O positive child is A positive what must father be?
The father can be A-, A+, AB-, or AB+
If the mom is o plus blood and so is the child what blood types can the father have?
The child inherits one allele from each parent for their blood type. You said that the mom is o+ and so is the child. Therefore: The father cannot have the following blood type genotypes: AB+, AB-, AA+, AA-, BB+, or BB-. The father's blood type genotypes can be: Ao+, Ao-, Bo+, or Bo-.
A women with AB blood has a child with AB blood The father has type o blood Is it possible he is the father?
no
Can a child be ab positive if the father is o negative?
No. If the child is AB, it must have inherited the A from one parent and the B from the other. If the father is O he has OO - and so cannot give the child an A or B.
Can o positive father and an ab positive mother have a negative child?
No, an O-group parent cannot have an AB-group child at all.
Can an a positive mother and ab positive father have an o positive child?
No, an O-group parent cannot have an AB-group child at all.
Is it possible for an ab positive child to have an o positive father?
No
Can an O-positive father and a B-negative mother have an AB-negative child?
No, an O-group parent cannot have an AB-group child at all.
