yes, through recessive genes and dominant genes
yes
the baby may be A or O.
Yes, it is possible for an AB positive parent and an O positive parent to have an O positive child. The child would inherit one O allele from the O positive parent and one A or B allele from the AB positive parent, resulting in an O positive blood type.
Generally speaking no, it would take both parents being A, B, or AB to produce an AB child.
no
If the father has an AB positive blood type and the mother has an O positive blood type, the possible blood groups for their child could be A or B. The A allele from the father can combine with the O allele from the mother to produce an A blood type, while the B allele from the father can combine with the O allele to produce a B blood type. The child cannot have an AB or O blood type in this scenario.
yes
No, an O-group parent cannot have an AB-group child at all.
No, an O-group parent cannot have an AB-group child at all.
The father can be A-, A+, AB-, or AB+
No, an O-group parent cannot have an AB-group child at all.
If the mother is O+, the child not be AB+ under any circumstances.
