By the presence or absence of two antigens.
Heredity determines blood type.
white blood cells
blood types are determined by proteins know as maker molecules
There are negative and positive of A, B, AB, and O. That means that there are 8 different blood types. Your blood type is determined based upon your mother and fathers blood types. O negative is the rarest blood type.
Blood types are not related to body types. Blood is determined by your parents. There are 4 maternal and 4 paternal blood type possibilites. That then gives you 16 different possibilites.
The American Red Cross website offers a lot of information on blood types. You can find charts on recipient-donor compatibility, blood types by population, and how blood type is determined. You can find this information at http://www.redcrossblood.org/learn-about-blood/blood-types
No, your personality has nothing to do with blood type. Your blood type is known before you are ever born and ever have a chance to show your personality. Your blood type is determined by your parents.
Blood types are hereditary. Your specific blood type is determined by the type of blood that your parents have. Remember that your blood type is determined by both your mom and your dad, so just because you have a specific blood type does not mean that your parents are the same or that your children will share your blood type.
Yes. Blood type is determined by the antigens present on the surfaces of red blood cells. There are three types of antigen, A, B and Rhesus. O blood types have neither A or B antigens. A types have A, B have B, and AB have both. Positive blood types have rhesus antigens, and negative blood types do not. Which antigens are produced is genetically determined.
Your blood type is inherited or given to you by your parents. The combinations of different blood types yields different blood types. In fact this is how paternity was once determined.
Blood type is determined by the type of antigen
The ABO blood group is determined by the presence or absence of specific antigen molecules on the surface of red blood cells. These antigens are determined by the inherited genes from our parents. There are three main types of antigens that determine the ABO blood group: A, B, and O. The combination of these antigens results in different blood types: A, B, AB, and O.
Eating differently does not affect your blood type. Your blood type is determined from the blood types of your biological parents, so it is genetic, not something that can be changed or acquired.
