Only if the father is a false O, but it's extremely rare. It's what happens when for some reason he doesn't produce the protein - in the case of your example, type A).

As for the negative, both parents have to carry at least one gene for it.

What will be the chald blood group if the father is ab positive and the mother is o positive?

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.

What is the expected genotypic ratio among children born to a mother having the genotype IAiO and a father with the phenotype A?

The mother will produce two types of gametes: IA and IO (mother is A) The father is AB his genotype is IAIB, thus he will produce these kind of gametes: IA and IB Four combinations are possible IA from Mother and IA from Father: The child has genotype IAIA and he has blood group A IO from Mother and IA from Father: The child has genotype IAIO and he has blood group A IA from Mother and IB from Father: The child has genotype IAIB and he has blood group AB IO from Mother and IB from Father: The child has genotype IBIO and he has blood group B Thus the phnotypic ratio is blood group A:B:AB = 2:1:1


Can a mother with blood group O and gather blood group AB produce O blood group child?

Can a mother has A positive blood type and a father has AB positive and the child has B positive?

Since both parents are Rh+, the child will also be Rh+.If the Mother is A0+ and Father is AB+, the child will be: AA+ AB+ AO+ or BO+ So yes this does produce a B+ child.If the Mother is AA+ and the Father is AB+, the child will be AB+ or AA+ neither of these is B+ so this doesn't produce a B+ child.


Could a female with B type and a man with AB type blood produce an offspring with O type blood?

Yes, an individual with blood type B can produce an offspring with blood type A. The explanation for this is that a mother with the blood type A can have a child with a father who has a blood type of A or AB and produce a child with type A blood.


Could a father with a blood group ab have a child that is O blood group?

Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
