it defines if the blood type is positive(+) or negative(-).
It is alsoreferred to as Rh factor in blood. So you've heard of someone saying they're type A blood or type O blood. You would put the Rh factor after that and it can be a positive (having Rh factor) or a negative (not having Rh factor). So an example would be A pos or O neg blood types.
type O and A is the type, you also have an Rh factor-either positive(meaning you have the factor) or negative(the Rh antigenis not present). All blood types can have a positive or negative rh factor so you need to know whether you and the father or RH positive or negative
The rH factor of blood determines if it's positive or negative. For instance, O+ is rH positive O-type blood. The universal donor between the AB type and the rH type is the AB positive blood type.
The O blood type is known as the universal donor, but there is one catch the Rh factor, people who are O - (people who don't have the Rh factor) can donate to anyone, but if the person if O+, then they can donate to anyone who is Rh +, so yes there could be a problem depending on the Rh factor.
rh negative is not a unique blood type. Rather, it means that the blood is missing the Rh factor that those with Rh positive blood. This is denotated by the word "positive" or "negative" that is said as part of the blood type, after the letter type, A, B, AB, or O.
The initials "Rh" stand for Rhesus factor, which is a protein found on the surface of red blood cells. This factor is important in blood typing, as individuals who have the Rh protein are considered Rh positive (Rh+), while those who do not have the protein are considered Rh negative (Rh-).
Yes, it is possible for a negative blood type parent and a positive blood type parent to have a negative blood type child. This can occur if the positive parent is heterozygous for the Rh factor gene, allowing for the possibility of passing on a negative Rh factor to the child.
Rh is not a blood type by itself but is just one part of what makes up a blood type. There are two parts to blood typing: the ABO aspect and the Rh factor. One has blood type A, B, AB, or O, AND then is either Rh positive, or Rh negative. Hence why you hear blood types like A positive, O negative, etc. The positive/ negative is referring to the Rh factor. Rh positive is dominant, so one only needs one Rh positive parent so be Rh positive. Rh negative is recessive. If both parents are Rh negative, the child they have must be Rh negative as well. To know what blood type you could be, you need to know your parents' entire blood type.
B and Rh are two different blood type systems. The B blood type refers to the presence of the B antigen on red blood cells, while the Rh factor (Rh positive or Rh negative) refers to the presence or absence of the Rh antigen. This means someone could have blood type B+ or B-, indicating their blood type in both systems.
The traits for blood type and Rh factor are determined by the presence or absence of specific proteins on the surface of red blood cells. Blood type is determined by antigens (proteins) on the red blood cell membrane, while the Rh factor is based on the presence or absence of the Rh antigen (protein) on the red blood cell.
O Rh D positive refers to a blood type that is O positive and Rh positive. In this blood type, the individual has O type blood with Rh factor present on the red blood cells. This is one of the most common blood types among the population.
Rhesus (Rh) factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you're Rh positive. If your blood lacks the protein, you're Rh negative. Rh positive is the most common blood type.
