Yes, siblings can have different blood types. This is because a person’s blood type is determined by the combination of two alleles inherited from the parents. Each parent gives their child one allele from each of their two alleles.
Depending on which combination the child inherits, their blood type could be different from their siblings’. For example, a mother with type A blood, who has two A alleles, and a father with type B blood, who has one B allele and one O allele, could have a child with A, B, AB, or O blood type.
So, even if all of their children are born with type A blood, their next child could have a different blood type.

Can a child have a different blood type than both parents?
Absolutely. A child’s blood type is determined by the specific combination of genes that have been inherited from their parents. It is entirely possible for a child to have a different blood type than either of their parents due to variations in the genetic material associated with each parent.
Specifically, this is because the gene pair that determines each person’s blood type is considered to be variable, meaning the two parents can each pass down a different variation of the gene pair. When these two different variations of the gene pair combine, it is possible for the child to have a blood type that is different than either parent.
While it is likely that two parents with different blood types will result in their child having a third, distinct blood type, it is possible for two parents with the same blood type to also have a child with a different blood type.
What are the 3 rarest blood types?
The three rarest blood types are AB-, A- and B-. These rarer blood types are also known as “minor” blood types and are found in less than 5% of the population. AB- is the rarest of all the blood types, and is only found in 0.
5-1% of individuals. In comparison, the more common blood types, A+, B+ and O+, are present in 31%, 9% and 39% of people, respectively.
People with rare blood types are often in high demand for blood transfusions for patients who require complex surgeries and treatments. As such, it is important for people with these rare blood types to make sure they register with their local blood bank in order to ensure that there is an adequate supply available in the event of an emergency.
In addition, donating blood and registering as a volunteer donor are important ways for individuals to help and contribute to the community.
Which parent determines your blood type?
Neither parent determines your blood type; rather it is determined by a combination of your parents’ genes. Any person can have any of the four main blood types: A, B, AB and O. Each of these types is determined by two alleles or genes.
People receive one of each gene, one from each parent. Depending on which gene is dominant and which is recessive, you will get either a positive or negative version of a blood type. For example, if you are type O then you have two recessive alleles, one from each parent.
People with positive blood types (A,B, and AB) have at least one dominant allele. Therefore, both of your parents have to have the genes they possess in order to pass them on to you, but it is the combination of their genes that determines your type.
Can 2 parents with type A blood have a child with type O blood?
Yes, two parents with type A blood can have a child with type O blood. This is because of the ABO blood group system, which is based on the presence or absence of certain proteins, called antigens, on the surface of red blood cells (RBCs).
Type A blood has A antigens, type B blood has B antigens, type AB blood has both A and B antigens, and type O blood has no A or B antigens.
While it may seem like parents with blood type A would only be able to give their children type A blood, it is actually possible for them to have a child with type O blood. This is because each parent passes down a copy of their version of the A and B genes, which determine the type of antigens expressed on their RBCs.
The combination of these two copies of the gene can result in a ‘mismatching’, where one parent will pass down A, and the other will pass down a non-A gene.
An example of this type of mismatching is when two parents with type A blood pass down an A and a non-A gene for their child. Since the non-A gene is recessive, the child will express type A antigens, like the type A parents.
However, the child’s RBCs will not have any B antigens, so they will have type O blood instead.
In summary, two parents with type A blood can have a child with type O blood if they both pass down one copy of the A gene and one copy of the non-A gene.
What 2 blood types are not compatible for pregnancy?
When considering blood type compatibility for pregnancy, it is important to understand that blood types are classified as either A, B, AB or O. In general, a baby’s blood type is directly related to the mother’s and father’s blood type.
For example, if the mother is type A, and the father is type B, the baby will be type AB. However, if the mother is type O and the father is type A, the baby can still be type A or type O, since type O is the universal donor and is compatible with any other blood type.
When it comes to blood type compatibility for pregnancy, two blood types that are not compatible are type A and type B. This is because type A and type B are both antigenic, meaning that if a pregnant woman has one of these two blood types, her body will produce antibodies against the other type.
These antibodies can cause negative changes in the fetal blood cells, leading to anemia and other complications in the fetus. Therefore, if a woman is pregnant and is type A or type B, it is important to ensure both parents have the same blood type to avoid any potential issues.
Can a child have blood group O if parents have blood group A and B?
Yes, a child can have blood group O if their parents have blood group A and B. This is due to the inheritance of the antigens A and B from the parents. When both antigens A and B are passed onto the child, the two combine to form a kind of a hybrid antigen that is called O antigen.
When the O antigen is expressed in the child’s blood type, the result is blood group O. This is why some parents with blood group A and B can have a child with blood group O.
Do babies always have the father’s blood type?
No, babies do not always have the father’s blood type. This is because blood types are determined by genes inherited from both the mother and the father. Each gene may be either dominant or recessive, and it can be different in the mother and father.
For example, if the mother has one O gene and one A gene, and the father has one A gene and one B gene, the gene from the father may or may not be expressed in the baby. Depending on which genes are dominant, the baby may receive an A, B, AB, or O type.
If the father’s gene is recessive, the baby may not have the same blood type as the father.
Does the mother or father determine a child’s blood type?
No, neither the mother nor the father determine the blood type of a child. Blood type is determined by genetics, the combination of the mother and father’s genes. Each parent passes one of their two ABO alleles onto the child at conception.
The combination of those ABO alleles then determine the child’s ABO blood type. For example, if the mother has an A and B allele, and the father has an A and O allele, then the child might have a Type A, Type AB, Type B, or Type O blood type.
However, it is impossible to predict which exact blood type the child will have since the ABO alleles influence each other in complex ways.
What genes are inherited from father only?
The answer to this question is complicated and depends on a number of factors. In general, genes can be inherited from both the father and the mother, as well as from any combination of the two. Some specific genes, however, can only be inherited from the father.
These are known as Y-linked or paternal genes, and they are carried only by the male members of a family. Examples of Y-linked traits include baldness, the loss of forehead wrinkles and the presence of a widow’s peak.
Other traits, such as earlobe shape and the dry or wet earwax type, may also be Y-linked. In addition, some diseases such as Duchenne muscular dystrophy, factor VIII deficiency (hemophilia A), and some cases of male infertility are associated with paternal genes.
Finally, some genetic tests are designed to study Y-linked paternal traits.
Do you get more DNA from your mother or father?
It is impossible to definitively say whether one gets more DNA from their mother or father, as the specific genetic contributions depend on individual biological circumstances. Every person has a unique combination of maternal and paternal DNA, and the ratio of each person’s parental DNA can vary significantly.
In humans, eggs from the mother provide the entire genetic contribution from the mother, whereas sperm from the father only carries half their father’s DNA. This means that certain parts of each person’s biology will always be 100% maternal, such as their mitochondrial DNA, which is found in all cells of the body and is responsible for producing energy.
Other parts will always be 50/50, such as the nuclear DNA that makes up chromosomes, inherited in equal parts from both parents.
Given the variations in biology and the fact that humans have 23 pairs of chromosomes, which contain innumerable genes, it is impossible to accurately know how much genetic material a person gets from their mother or father.
Ultimately, the contribution of each parent’s DNA is unique to every individual and impossible to accurately quantify.
How much of the same blood do siblings have?
Siblings typically share around 50% of the same DNA, because they get half of their DNA from each parent. However, the amount of DNA shared by siblings can vary slightly depending on which genes they inherited from their parents, as well as their own unique mutation patterns.
In some cases, siblings may have as much as 80% identical DNA, while in other cases, the percentage of shared DNA may be much lower. Overall, siblings tend to share at least 50% of the same genetic material.
