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 you have two blood types O and a?
Just like eye or hair color, our blood type is inherited from our parents. 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. Click to see full answer. Also asked, can two blood type O make a Type A?
Why would a baby with only one blood type be O/O?
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). Rh positivity can come from three different gene combinations: +/+, +/-, and -/+.
Can two people with a and B blood types have a child?
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.
What blood types can be produced when one parent has a?
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 an O and B cross produce an A or AB child?
Can two O parents have a child with A blood?
Can a parent with AB and O have a child with blood type A?
Can an A+ parent have an O+ child?
Is ABO blood type inherited?
Can two Type O parents have a Type A?
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 do 2 O+ parents make?
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.
Can a child have a different blood type than both 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+ have an A+ baby?
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.
What blood types make an 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 if both parents are O+?
Blood type O is homozygous for the gene 'i', their genotype is 'ii'. 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-.
CAN A and O+ have a baby?
Could you please explain if it is possible for a father who has O positive blood and a mother with A positive blood to have a baby with O negative blood? I am a little confused and have been trying to research the answer. I would appreciate if you are able to assist. Yes this is definitely possible.
Can an O positive father have an AB child?
In most cases, an O parent and an AB parent will have only A or B kids. I added a table at the end of this answer that has all blood type combinations for two parents plus the possible blood types for their children. Exceptions to these rules are extremely rare. (Though not impossible.
What is the rarest blood type?
AB negativeWhat's the rarest blood type? AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood.
Can a brother and sister 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.
How do I find out my blood type without a test?
Without drawing blood A person may be able to use a saliva sample to test for their blood type. Around 80% of people produce the relevant antigens in their saliva. According to 2018 research , if a person secretes these antigens in their saliva, a dried saliva sample can reliably indicate their blood type.
Can two O blood types make an A? - Quora
Answer (1 of 6): No, two people with type O blood can only produce offspring with type O blood. To be type O, you must have a genotype of OO because the O type is recessive. Type A blood can result from either AA or AO. Two people with type A blood could produce a type O offspring, but not the ...
Can two o+ parents have an a+ baby? - eNotes.com
For humans, blood type is determined by three possible alleles which are A,B, and O. The child's blood type is dependent on which two alleles are inherited by the offspring from the parents' gametes.
If Both Parents Have O Blood Type Can Their Child Have A?
Answer (1 of 11): If both parents have O blood it is this genotype. OO There is NO WAY a mating of two O type humans can yield any other type (A or B)Only extramarital matings could do this. There must be either one or the other dominant allele ( A or B )O is recessive and only expresses in the homozygous condition. OO Those of you who are saying otherwise are either mistaken about the blood ...

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.
Can two blood types produce a child?
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.
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.
Can one parent have AB and another with B?
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.
Can a person have a blood type with a Rh gene?
Therefore, a person may have a Rh + blood type and can still have an Rh - gene (See the chart below). Furthermore, 2 parents with Rh + blood types can have a child with Rh - blood type. Genotype (DNA) Blood Type. (+ , -) or (+ , +)
What is the difference between ABO and O blood type?
Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.
How many ABO genes are there in a child?
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. 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 ...
When do you develop antibodies?
By the time you are six months old , you naturally develop antibodies against the antigens your red blood cells lack. For instance, a person with A blood type will have anti-B antibodies, and a person with B blood type will have anti-A antibodies. If you have type A blood, you cannot receive B blood because your body's anti-B antibodies will fight ...
Why is Type O blood so common?
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 .
What are the 8 blood types?
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- ). Click on a blood type below to learn more.
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.
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 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.
Which group has no antigens?
Group A. has neither A nor B antigens on red cells (but both A and B antibody are in the plasma) has both A and B antigens on red cells (but neither A nor B antibody in the plasma) has only the B antigen on red cells (and A antibody in the plasma) has only the A antigen on red cells (and B antibody in the plasma) B.

Can an A+ parent have an O+ child?
An A+ parent and an O+ parent can definitely have an O- child. Furthermore, can a child have a different blood type than both parents? 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.
Is ABO blood type inherited?
Everyone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). Just like eye or hair color, our blood type is inherited from our parents. 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. Click to see full answer.
