If both parents have O blood type, then their child could potentially be O positive. However, if one parent is type O and the other is type A, B, or AB, then that parent can pass the gene for O type blood to the child.
If one parent is O and the other is A, the child can either be A or O positive. For parents with type O and type B, the child could be either B or O positive. Lastly, if one parent is O and the other is AB, the child could be A, B, AB, or O positive.
All in all, the parent blood types that make O positive can vary depending on each parents’ own respective blood type.

How did the baby inherit type O positive blood?
In order for a baby to have blood type O positive, they must have inherited the O gene from one of their parents. This means that one of the parents must carry a gene that codes for O blood. Type O positive blood itself is a result of an inheritance of two O type genes, one from the mother and one from the father.
The two O type genes make the protein antigen expressed on the outside of red blood cells an O antigen, which then creates type O positive blood. As red blood cells carry the genetic information from each parent, the baby’s blood type can be determined based on the genes that the baby receives from their parents.
Can a mom and a+ dad have a O+ baby?
Yes, a mother and father who are both O+ blood type can have a baby with an O+ blood type. This is because the O blood type is a dominant type, meaning it can mask the blood type of any other gene it is paired with.
Parents with O+ blood type can pass on either the O allele or the + allele (or possibly both) to their child. Thus, it is possible for two O+ parents to have an O+ baby.
What causes O positive babies?
The cause of O positive babies is the genetic inheritance of blood type from the parents. Each person has an inherited blood type that is determined by their parents’ blood types. Depending on the combinations of the four different blood types (O, A, B, and AB) that the parents possess, the baby’s blood type can be O+, A+, B+, AB+, O-, A-, B-, or AB-.
To determine the baby’s blood type, the attribute of each parent’s blood type must be examined. O positive is the most common form of blood type, and is caused when one parent passes on an O gene and the other passes on a positive gene, meaning both parents have either A+, B+, or O+.
It’s also possible for both parents to pass on the O+ blood type, which will result in the baby having an O+ blood type as well.
In some cases, it’s possible for the baby to possess a different blood type than their parents, which is known as a “blood group mismatch”. This occurs when the genes that are passed on from each parent do not match up, resulting in the baby having a different blood type from the parents.
Do babies always have the father’s blood type?
No, babies do not always have the father’s blood type. Blood type is determined by a combination of genetic factors inherited from both the mother and the father. Each parent contributes two alleles – one from the mother and one from the father.
The alleles will determine the baby’s blood type. For example, if the mother is A+ and the father is B+, the baby could be either A+, B+, AB+ or O+. There are other combinations possible depending on the blood types of the mother and father.
Therefore, babies do not always have the father’s blood type.
How rare is it to be O positive?
It is fairly common to be O positive, as it is the most common blood type in the world. According to the American Red Cross, 38% of the population in the United States and 40% of the population in Europe have O positive blood.
This makes O positive the most common blood type in the world, with AB negative being the rarest. Furthermore, out of all the blood types, O positive is the only universal donor and can be used for any recipient, making it a very valuable type.
How is blood group O inherited?
Inheritance of blood type O is based on an individual’s ABO blood type genes, which are inherited from both parents in a specific combination. The ABO genes are passed on from each parent in different combinations, depending on each parent’s dominant ABO gene.
If both parents have an O blood type, the child will also have an O blood type.
The ABO gene responsible for blood type O is a recessive gene, meaning that in order for the O blood type to appear, both parents must pass down their O gene. If one parent has an A, B, or AB blood type and the other has O, the child will most likely have an A, B, or AB blood type.
In some cases, if two ABO genes are passed down in equal combination, the offspring will display one of the two parental ABO groups. For example, if both parents have type A and type O blood, the offspring will most likely be type A, but there is a chance they may be type O depending on the combination of the genes.
In summary, the inheritance of the O blood type is complex and considered to be a recessive gene. If both parents have an O blood type, the child will also have O. If one parent has an A, B, or AB type blood and the other has O, the offspring will likely have A, B, or AB.
Occasionally, when both parents have A and O blood types in equal combinations, the child may be type O depending on the combination of the genes.
Can you have type O blood if your parents don t?
Yes, it is possible to have type O blood even if both of your parents don’t. Blood type is determined by the combination of alleles inherited by an individual from their parents. There are two alleles that determine a person’s blood type — A and B — and they can be inherited either as two dominant alleles (AA or BB) or one dominant and one recessive (AO or BO).
If both of your parents have the same allele (either AO or BO), then you will have the same blood type they do. However, if they have different alleles (AA and BO, or BO and AO) then you could have either type A, B, AB or O.
So, even if neither of your parents have type O blood, it is still possible for you to have it.
Can a child have O blood if neither parent does?
Yes, it is possible for a child to have O blood if neither parent does. This is due to a phenomenon called “blood phenotyping,” or the mixing of genetic traits evident in the blood. This can occur when both parents carry different alleles for a given blood type.
If both parents carry a copy of the O allele for a particular blood type, it is possible for the alleles to combine in the child and result in O blood type. Similarly, a child can have a blood type other than either parent’s if there is a mix of their alleles.
Since the alleles that codes for O blood type is recessive, it is possible to be a carrier of the O blood type allele even when the A, B and AB alleles are dominant.
What parents can produce blood type O?
Parents who are both blood type O can produce a child who is also blood type O. This is because both blood type O parents carry the genotype io which is the recessive allele for both A and B. Therefore, there will be no A or B allele passed on to the child and the offspring will be blood type O.
As both parents carry the recessive alleles, there is a higher chance for the child to inherit the two recessive alleles, giving the child blood type O.
Do both parents have to be O for child to be O?
No, for a child to be O-type, only one parent must be O-type. It is possible for both parents to be either A or B-type and still have a child with O-type blood. This is because the O-type blood is a recessive gene, meaning that even if both parents are neither O nor A or B, they can still pass on the O-type gene.
If both parents can pass on the O-type gene, it increases the chances of the child inheriting the O-type blood. However, it is also possible to have a child with O blood if only one of the parents carries the O-type gene.
In this case, the child will have a 50% chance of inheriting the O-type blood.
How do you get blood type O?
Blood type O is the most common blood type in humans, and it is sometimes referred to as the “universal donor” type due to its ability to be transfused into any other blood type. It is determined by the presence or absence of certain antigens on the surface of red blood cells.
If a person does not have any antigens present, then they have type O blood. If a person has A and B antigens present, then they have a positive blood type and if only A is present, then the person has type A blood, and if only B is present, then the person has type B blood.
People who have both A and B antigens present have type AB blood. It is important to note that a person can only have a specific blood type if it is inherited from one of the parents, who must both have the same blood type.
It is not possible to get blood type O from blood transfusions or by taking any type of medication or supplement.
Can I be O positive if my parents aren t?
Yes, it is possible for you to be O positive even if your parents are not. Blood type is determined by a combination of your parents’ blood types, so it is possible for you to have a different blood type than either of your parents.
The O positive blood type is one of the most common blood types, so it is possible to inherit it even if neither of your parents have it. Blood type is determined by a gene on chromosome #9, which is inherited from your parents, but it is possible that a mutation in the genetic code could cause you to have a different blood type than either of your parents.
It is also possible to acquire the O positive blood type through a blood transfusion if you are not born with it.
Can a child have blood group O if parents have blood group A and B?
Yes, it is possible for a child to have blood group O if the parents have blood groups A and B. This is because blood type is determined by genetic inheritance and it is possible for the child to inherit either one of the parents’ blood types, a combination of their blood types, or even a completely different one.
Blood group O is actually considered to be the “universal” blood type, meaning that it can be passed to any offspring regardless of the blood type of either parent. The other blood types—A, B, and AB—are ALL recessive blood types, meaning they can only be passed on if both parents carry the same recessive blood type.
Therefore, if both parents carry blood groups A and B, the child can inherit blood group O or a combination of A and B, or even one of the two individually.
What are the 3 rarest blood types?
The three rarest blood types are bombay (h/h) type, the england and wales (ew) type, and rosa 27 (or ors) type. The Bombay (h/h) blood type is extremely rare and believed to only exist in a few pockets of India and Pakistan.
On the other hand, England and Wales (EW) blood type is mainly found in England and Wales. This type is also uncommon and found in mainly northern Europe and isolated communities. Rosa 27 (or ORS) blood type is the rarest blood type and is believed to be particularly unique.
It is present in only the South American indigenous population, specifically the Quechua people of Peru and Bolivia. The Rosa 27 (or ORS) blood type is very hard to match in a donor due to its rarity.
