- Rh Negative Blood Types: A-, B-, 0- and AB-. Rh factors are genetically determined. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance.

Being Rh Negative About 85% of the population in the United States has Rh positive blood, meaning that certain protein molecules are present on the surface of their blood cells. Your blood type (groups A, B, AB and O), as well as this Rh factor, is determined genetically. As Rh positive blood is a dominant trait, the majority of Rh negative women carry children with Rh positive blood. During birth and, occasionally, at other times, some of the baby's blood may enter the mothers' circulation.

- If the baby is born with AA or AO, that is type A blood. If the baby is born with OO, that is type O blood.   As for the Rh, that is the luck of the draw. The baby may inherit the negative from the mother or the positive from the father. More likely it will be Rh positive, but there is a chance that it would be negative.

Type and screen Blood Type Compatibility. 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.By the time you are six months old, you naturally develop antibodies against the antigens your red blood cells lack.he 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.

What determines your blood type? Best Answer: Your genotype determines your blood type before your born. There are three alleles or versions of the blood type gene: A, B, and O. Since everybody has two copies of these genes, there are six possible combinations; AA, BB, OO, AB, AO, and BO.h is not passed down from parents. With your parents having AB and O, you can only have type A or type B blood because O is recessive. You could have type O if your mother was AO or BO, but she isn't. Since you have type A, your blood is AO (A from your mother and O from your father... but A is dominant).

What determines your blood type? Everyone has two copies of chromosome 9 so you have two ABO genes. If both of them are the A alleles then your genotype (genetic makeup) will be AA. Your blood type will be A. If one of your ABO genes is the A allele and the other is the O allele then your genotype will be AO.

Can two A+ parents have an O+ child? Yes, a A+ bloodtype can have the genotype of AA or AO, so it is possible for the child to have blood type O+. http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/genotypes.html.

Blood type Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Blood group A individuals have the A antigen on the surface of their RBCs, and blood serum containing IgM antibodies against the B antigen. 2  Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.

Do you get your blood type from your parents? Best Answer: ABO blood type is determined by a set of codominant genes. A and B are codominant, and the absence of both is called O. If a person inherits A from one parent and O from the other, their genetic code is AO and the resulting blood type is A. A blood comes from AA or AO genetic code.

How does inheritance of blood types work? This is going to take some explaining. There are three blood genes: A, B, and O. (I'm going to ignore the + and - part of this.) A and B are dominant, and O is recessive. You inherit one blood gene from your mother and one from your father. The combination of genes determines your blood type. With that in mind, we turn to your question, Confused.

Why Canât You Use Blood from Someone Who Has a Different Blood Type Than You? 1 Everyone has one of four blood types – A, B, AB, or O – which is inherited from your parents. 2  Your blood type is determined by the presence or absence of two antigens – A and B – on the surface of red blood cells.A third antigen, called Rh factor, will either be present or absent. Antigens are substances that may trigger an immune response, causing your body to launch an attack if it believes they are foreign.hile all blood is similar in its components (such as containing red cells, platelets, and plasma), it also has important characteristics that make it unique. Your blood type is determined by the presence or absence of two antigens – A and B – on the surface of red blood cells.

Blood Type Genetics and Compatibility 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.

ENDMEMO Blood Type Genetic Basis: In genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive.So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is type AB.ince AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A. The +/- is called the rhesus factor, with + being dominant, and-being recessive.

ABO Incompatibility in Newborns 1 The baby's blood type is A, B, or AB. 2  Just like two blue-eyed parents can only have a blue-eyed child, parents with O blood type can only have a baby with blood type O type. 3  The presumed dad is not the real dad. 4  The baby's blood type is O. In this case the presumed dad might be the real father.

Blood Type Genetics A child's blood type can be predicted with a high degree of certainty from the parent’s blood types. To do that a “Punnet Square” is constructed. In a Punnett Square the alleles from one parent are listed on one side and the alleles from the other parent are listed on the top.he A allele encodes for an enzyme called N-acetylaminogalactosyltransferase which makes the A antigen that confers blood type A. A mutation on this gene conforms the B allele. This encodes for another enzyme that makes the B antigen and confers the blood type B to the carrier of this allele.

Blood Type Incompatibility or Jaundice Blood types are categorized by A, B, and O, and given an Rh factor of positive or negative. A-B-0 and Rh incompatibility happens when a mother’s blood type conflicts with that of her newborn child.

How is Blood Type Determined? So there are eight blood groups you can belong to: A Rh+, A Rh-, B Rh+, B Rh-, AB Rh+, AB Rh-, O Rh+, and O Rh -, although doctors usually leave out the Rh and just say + or -. What blood type a person ends up with is determined by genetics.f your blood cells stick together when mixed with: Anti-A serum, you have type A blood Anti-B serum, you have type B blood Both anti-A and anti-B serums, you have type AB blood If your blood cells do not stick together when anti-A and anti-B are added, you have type O blood.

Blood Type Calculator People have molecules called antigens on the surface of their red blood cells. The two most important ones are ABO system antigens and the Rh system. Our interactive blood group calculator determines baby's probable blood types for the ABO system based on mom's and dad's blood type, and vice versa: The ABO Blood Group System. 1  If you have A antigens covering your red cells then you have blood group A and you also have B-antibodies.

Blood Typing Blood types are based on the markers (specific carbohydrates or proteins) or antigens on the surface of red blood cells (RBCs). Two major antigens or surface identifiers on human RBCs are the A and B antigens. Another important surface antigen is called Rh. Blood typing detects the presence or absence of these antigens to determine a person's ABO blood group and Rh type.
