Yes. My son is 0- and my daughter in law is 0+ and they just had a A+ baby boy. It is very rare but the doctor said it can happen because every has a primary and secondary (recessive) blood gene. Since my d-i-law's father is A+ and her mother is 0+ and his parents are both 0+ but his mothers mother is A+ and her Father is 0+ there are many recessive A+ genes in their DNA blood type therefore they can have a A+ child. (Example mother is O+/A+ and father is 0-/A+ equals= A+/0 child.) 0 seems to be universal and can throw off a recessive gene. In our case; since it is rare; the baby and the mother's blood types caused him to have alot of jaundice (18) so he had to go back in hospital to be under the light for an additional 24 hours to bring it down. She was nursing and her milk had not come in to give him the fluids to fight off the excess billiruben count. Other than that; it will not be a problem for either of them.

As it is hard to find this information on the internet. Most sights say no because they are stating the normal without considering the recessive secondary gene type that are rare. Ask a doctor.... it happens

Yes, it is possible for an A+ father and a B- mother to have an O child biologically. Blood type inheritance follows specific patterns, and parental blood types do not directly determine the child's blood type. The child's blood type will depend on the combination of genes received from the parents.

Yes, it could be if both parents blood types are with Hetero alleles.

(I^Ai) and (I^Bi)

The ( i ) from father and ( i ) from mother will make (ii) --> which means O

Can type 0 plus mother and ab plus father have an O plus baby?

No. The child will be either group A or group B, but not group O. This is because the father can donate only a group A gene or a group B gene, so since group A and group B are dominant over group O, the child could not have group O blood.


Your fathers blood type is 0- and your blood type is O plus what blood time would your mother have to be?

Your mother would have to be type O negative for you to have a blood type of O positive. This is because the O blood type is recessive, so both parents would need to pass on the O gene for their child to have type O blood.


Can a A plus mother and a A plus father have O plus child?

No. The O+ gene is exclusive, meaning that if you are O+, your body only has the O+ gene, so your child can't be anything other than 0+ as well. He can only be A+ if the one of the parents is AB+ or A+.


What is the risk of a colour blind child in a family when father is colour blind and mother is normal?

If the father is color blind and the mother is normal, the risk of their child being color blind is 0% for daughters and 50% for sons. This is because color blindness is a sex-linked trait carried on the X chromosome, with the gene for color blindness typically passed from mother to son.


If your father is type o positive and your mother is type ab negative what is the possible blood type of a 6th child?

The possible blood types for the 6th child would be A or B positive, as those are the combinations of blood type alleles from the parents' genotypes. It is not possible for the child to have AB blood type, since the father does not carry the A allele.

Can parents with blood tipe 0 plus and 0- have a child with 0 plus blood?

I think that's the only blood type they can make. the doctor said it can happen because every has a primary and secondary (recessive) blood gene. Since my d-i-law's father is A+ and her mother is 0+ and his parents are both 0+ but his mothers mother is A+ and her Father is 0+ there are many recessive A+ genes in their DNA blood type therefore they can have a A+ child. (Example mother is O+/A+ and father is 0-/A+ equals= A+/0 child.) 0 seems to be universal and can throw off a recessive gene. If one parent is 0+/0- and the other parent is 0-/0+ then the child can take the 0+ or 0- gene type.

Can type 0 plus mother and ab plus father have an O plus baby?

No. The child will be either group A or group B, but not group O. This is because the father can donate only a group A gene or a group B gene, so since group A and group B are dominant over group O, the child could not have group O blood.

Your mother would have to be type O negative for you to have a blood type of O positive. This is because the O blood type is recessive, so both parents would need to pass on the O gene for their child to have type O blood.


Can a child be A positive if father is A negative and mother 0 positive?

Yes, the child of these parents could have either blood type O+, O-, A+, or A-.


Can a mother of AB blood and a father that is O blood have a child with 0?

Yes, it is possible for a mother with AB blood and a father with O blood to have a child with O blood type. This is because the parents can each pass on an O allele, resulting in a child with O blood type.


If mother is 0 positive and baby is a positive what is father?

The child can receive blood type parts from either parent, but must receive one half from the mother and one half from the father. As such, because the mother has neither A nor B, and the child has A, the father must have the A type in his blood, meaning he's either A type or AB type.
