The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A. For instance, a parent with O blood with 2 O genes and a parent with A blood with 2 A genes will have an A blood type child with one A gene and one O gene.
What blood types make an A baby?
Therefore: Two parents with blood type A will have a baby with either A or O. Two parents with B blood type will have a baby with either B or O. Two parents with blood type AB will have a baby with either A, B, or AB.
What blood type will a baby have if both parents are O positive?
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.
What two blood types can make a?
Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types.
Can a child’s blood group be different from the parents?
The blood group of offspring can be different from their parents. There can be many permutations and combinations according to the genotype of the parents. E.g. If both parents have AB blood type, there are chances of offspring having A, B or AB blood type.
Can two O positive parents have an A negative child?
Yes this is definitely possible. In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.
Can two O+ make an O?
Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.
Can siblings have different blood types?
No, siblings don’t necessarily have the same blood type. It depends on the genotype of both the parents for the gene determining the blood type. E.g. Parents with the genotype AO and BO can have offspring with blood type A, B, AB or O.
Can two O positive have a baby?
Theoretically yes, but it would be extremely rare. Two O parents will get an O child nearly all of the time.
What is special about O positive?
O+ blood is very important as a (mostly) universal red blood cell type. This blood type can be used in emergency situations such as traumatic bleeding or other types of emergency transfusions. It is also an important blood type as type “O” patients can only receive type “O” red blood cell transfusions.
Which blood group should not marry?

What is the golden blood type?
Fewer than 50 people worldwide have “golden blood” — or Rh-null. Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system. It is also very dangerous to live with this blood type, as so few people have it.
What blood types should not have babies together?
When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.
Is O positive a rare blood type?
O positive is the most common blood type as around 35% of our blood donors have it. The second most common blood type is A positive (30%), while AB negative (1%) is the rarest.
Is O Negative the rarest blood type?
Contrary to popular belief, O- blood is not the rarest blood type. It is estimated 7 percent of the population has O- blood type while only 1% of the population has AB- blood.
Can parents have the same blood type?
Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent’s blood type.
How do I find out my blood type without a test?
- Ask your parents or doctor.
- Blood draw.
- At-home blood test.
- Blood donation.
- Saliva test.
What is it called when mom and baby have different blood types?
Rh disease occurs during pregnancy. It happens when the Rh factors in the mom’s and baby’s blood don’t match. It may also happen if the mom and baby have different blood types.
Does the father and child have the same blood type?
While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!
How is O blood type inherited?
Blood Inheritance
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.
Could a man with O blood type be the father of an AB child?
Answer and Explanation: A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type.
What happens if husband and wife have same blood group O?
It will not create any problems during the birth of the first child. But in the case of childbirth, the Rh-antibody created at the time of birth of the previous child could break the embryonic placental barrier. As a result, additional bleeding or dead child may be born during the birth of a second child.

A woman’s blood group could influence her chances of getting pregnant, scientists have found. Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
Can your blood type cause a miscarriage?
Rh factor: Miscarriage can be caused because of the incompatibility of the mother’s blood and the blood of the unborn foetus commonly known as Rh factor incompatibility. This type of miscarriage occur when the blood type of mother is Rh negative, and the foetus blood type is Rh positive.

Only 7% of the population have O negative blood. Due to the its versatility for transfusions, it is in high demand. In an emergency, it is the blood product of choice. For example, just one car accident victim can require up to 100 units of O neg.
Who has the golden blood type?
The golden blood type or Rh null blood group contains no Rh antigens (proteins) on the red blood cells (RBCs). This is the rarest blood group in the world, with less than 50 individuals having this blood group. It was first seen in Aboriginal Australians.
What is the oldest blood type in the world?
