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.
Can two O blood type parents have a baby?
O blood type. For example, two O blood type parents can produce a child with only O blood type. 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.
What blood types can be produced by two different parents?
One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types. Rh Positive (Rh+) and Negative (Rh-) Blood Types
Can a person with blood type 0 have type a?
The way the AB0 blood type works requires that a person with blood type 0 cannot have any genes coding for A or B, because type 0 is recessive. So a type 0 person literally has no information of type A to pass on to their offspring, it would have to spontaneously develop.
Why is Type O blood type in short supply?
Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
Can two blood type O make a Type A?
For example, two O blood type parents can produce a child with only O blood type. 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.
Can 2 O+ Make a O?
A. 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.
What two blood types make a?
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.
Can a couple with both blood type A produce a type O child?
Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there's 1 in 4 or 25% chance for a child to have OO, or blood type O.
Can 2 O positive parents have an A+ child?
But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is even more unlikely). In fact, a child can get almost any kind of blood type if you consider the rule-breaking exceptions.
Can two O positive have a baby?
Two parents who have O positive blood could easily have a child who is O negative. In fact, most children who are O negative have parents who are positive, since the +- combination is so much more common than the — combination.
What blood types make a+ baby?
If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor....If you have type A blood, your parents had one of the following possible combinations of blood types:AB and AB.AB and B.AB and A.AB and O.A and B.A and A.O and A.
What are the 3 rarest blood types?
The rarest blood types are: B negative(B -ve), which is found in 1.5 percent of the total population. AB negative(AB -ve), which is found in 0.6 percent of the total population. AB positive(AB +ve), which is found in 3.4 percent of the total population.
Which parent determines the blood type of the child?
A child inheriting an O from each parent will have type O blood. If the biological mother gives an A gene for blood type and the biological father gives an A gene for blood type, the child will have type A blood. “If the genes passed down are AA, the blood type shows up as A,” says Seitz.
What happens if husband and wife have same blood group O?
When the female is O negative and male is O positive, there is a future risk for the fetus with a condition called as hemolytic disease of newborn. If both are O positive then there is no risk.
Which 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.
What will never be fathers blood?
question. The father's blood group cannot be 'AB' if the mother has blood group 'B' and child blood group is 'O'.
Which parent determines the blood type of the child?
A child inheriting an O from each parent will have type O blood. If the biological mother gives an A gene for blood type and the biological father gives an A gene for blood type, the child will have type A blood. “If the genes passed down are AA, the blood type shows up as A,” says Seitz.
What is the rarest blood type?

Is O a good blood type?
Over 80% of the population has a positive blood type and can receive O positive blood. That's another reason it's in such high demand. O positive donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

O+The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.
Can 2 O positives make an A?
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.
Can two O parents have an A baby?
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.
Can 2 O positive parents have an A negative child?
Yes, Mom or Dad may be positive, but that recessive negative gene is still floating around in his or her DNA. If it becomes paired with another negative gene from a similar positive-negative parent, that child will be negative even though both parents are positive. It's an everyday occurrence, says pediatrician Dr.
What happens if both parents are O positive?
So, if the parents have the O blood group then all the children will have the O blood group only.
What blood types should not have babies together?

Do all siblings have the same blood type?
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.
Why is the O-type antigen masked?
This is mostly due to the fact that the 'O-type' antigen is masked by the presence of an A- or B-type antigen. This is explained in the following chart, showing the different the genotypes that make up the blood types. For example, two O blood type parents can produce a child with only O blood type.

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.
Can two O Negative parents have a positive child?
No, because to be rh negative, one must have TWO rh negative alleles. The rh factor is recessive. If both parents are rh negative, they must have ONLY rh negative alleles. Therefore they do not have any positive alleles to pass on to their children.
What is the possible blood type if both parents are O?
So, if the parents have the O blood group then all the children will have the O blood group only. Rh factor positive parents can be heterozygous for the gene so in that case, the children can be either O+ or O-.
How can an O blood type have a child?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

No: This genetic type is not possible with the blood type of the parents mentioned.
Can a baby have type O blood?
Using : Using the ABO blood typing system- two parents with type o blood would have a baby with type o blood. The baby may or maynot be rh positive. Because : Because neither parent has a gene for the a blood type (both are o/o in order to have type o blood) the baby could only have type o blood (with the same o/o genes).

How are blood types determined?
Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body . Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.
What Is A Rare Blood Type?
There are more than 600 other known antigens, the presence or absence of which creates " rare blood types ." Your blood type is considered rare if you lack antigens that 99% of the people are positive for . If you somehow lack an antigen that 99.99% are positive for, your blood type is extremely rare.
Why is the need for O negative blood the highest?
However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.
How many blood groups are there?
There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types ( A+, A- , B+, B- , O+, O- , AB+, AB- ).
How many lives are saved by blood transfusions?
Each year 4.5 million lives are saved by blood transfusions. There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death. Every 2 seconds someone in the US needs a blood transfusion.
Which group can donate red blood cells to A's and AB's?
Group A can donate red blood cells to A’s and AB’s. There are more than 600 other known antigens, the presence or absence of which creates "rare blood types.". Certain blood types are unique to specific ethnic or racial groups.
Why is the O-type antigen masked?
This is mostly due to the fact that the 'O-type' antigen is masked by the presence of an A- or B-type antigen. This is explained in the following chart, showing the different the genotypes that make up the blood types. For example, two O blood type parents can produce a child with only O blood type.

Is rh positive or negative?
Rh Positive (Rh+) and Negative (Rh-) Blood Types. The Rh (+/-) factor is inherited separately from the ABO blood types. Similarly to the masking effect of the O gene in ABO blood types, the Rh negative (Rh-) gene is also masked by the presence of a Rh positive (Rh+) genotype. Therefore, a person may have a Rh + blood type ...
