The Rh Factor Most people have Rh-positive blood, meaning that they produce the Rh factor, an inherited protein found on the surface of their red blood cells. But about 15 percent of the white population and 7 percent of the African-American population lack the Rh factor. These people are Rh-negative. The health of an Rh-negative person is not affected in any way. However, an Rh-negative woman is at risk of having a baby with Rh disease if she conceives a baby with an Rh-positive father and the baby inherits the father's Rh-positive blood type.

The Rh Factor: How It Can Affect Your Pregnancy What is the Rh factor? Just as there are different major blood groups, such as type A and type B, there also is an Rh factor. The Rh factor is a protein that can be present on the surface of red blood cells. Most people have the Rh factor—they are Rh positive. Others do not have the Rh factor—they are Rh negative.

- Rh factor: An antigen found on the surface of red blood cells. Red blood cells with the antigen are said to be Rh positive (Rh+). Those without the surface antigen are said to be Rh negative (Rh-). Blood used in transfusions much match donors for Rh status as well as for ABO blood group, as Rh-patients will develop anemia if given R+ blood. Rh typing is also important during abortion, miscarriage, pregnancy, and birth, as mother and fetus may not be Rh-compatible. Rh stands for rhesus monkeys, in whose blood this antigen was first found. See also RhoGAM, Rh incompatibility.

Blood Type Chart: Facts and Information on Blood Group Types In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent (–). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.1  The universal red cell donor has Type O negative blood type. 2  The universal plasma donor has Type AB blood type. positive is the most common blood type. Not all ethnic groups have the same mix of these blood types. Hispanic people, for example, have a relatively high number of O’s, while Asian people have a relatively high number of B’s.

Does Rh Negative Blood Type Equal Alien Heritage? The Basque people of Spain and France have the highest percentage of Rh negative blood. About 30% have (rr) Rh negative and about 60% carry one (r) negative gene. The average among most people is only 157%-Rh negative, while some groups have very little.

Blood Types in Pregnancy If a person has the genes + +, the Rh factor in the blood will be positive. If a person has the genes + -, the Rh factor will also be positive. If a person has the genes - -, the Rh factor will be negative. A baby receives one gene from the father and one from the mother.

Does Rh Negative Blood Type Equal Alien Heritage? For example: Basques are believed to have been the originators of the RH negative blood factor – the original genetic pool from which this factor came. While RH negatives are a small minority in the “white” and other races, and practically non-existent in “orientals”, the current Basques still are over 33 % RH negative.

- Rh factor is a phenotype similar to the blood type. Positive is dominant and so the possible genotypes are ++ or +-, whereas for negative it can only be --. If the parent … s are both +- they can produce ++, +-, or --. There is a 25% chance that these parents would have an O-child.

Rh Factor As part of your prenatal care, you will have blood tests to find out your blood type. If your blood lacks the Rh antigen, it is called Rh-negative. If it has the antigen, it is called Rh-positive. When the mother is Rh-negative and the father is Rh-positive, the fetus can inherit the Rh factor from the father. This makes the fetus Rh-positive too.

Rh Factor 1 More than 85% of people are Rh positive. 2  The Rh factor does not affect a person’s general health.  Problems can occur during pregnancy when the baby’s blood has the Rh factor and the mother’s blood does not, however it can be prevented in most cases with the medication called immunoglobulin (RhIg).

Why Are African-Americans at Greater Risk for Heart Disease? Four risk factors are the strongest predictors of heart failure: high blood pressure (also called hypertension), chronic kidney disease, being overweight, and having low levels of HDL, the good cholesterol. Three-fourths of African-Americans who develop heart failure have high blood pressure by age 40.

- Rhesus factor (rh) is a blood product – it’s a substance found in blood. Approximately 85% of the population has the rhesus factor and the remaining 15% percent do not. It is symbolised by the plus or minus after your blood group, for example, A-is rhesus negative and A+ is rhesus positive.

Blood type Rh disease can develop in these cases. Rh negative blood types are much less common in Asian populations (0.3%) than they are in White populations (15%). The presence or absence of the Rh(D) antigen is signified by the + or − sign, so that, for example, the A− group is ABO type A and does not have the Rh (D) antigen.

Aprovocative African Americans have higher rates of disability and consequently are more likely to receive benefits from the Social Security Disability Insurance (DI) program. African Americans make up approximately 13 percent of the American population; however, they represent 17 percent of DI beneficiaries. In general, workers with a higher probability of becoming disabled have a higher benefits-received-to-taxes-paid ratio than those who are not disabled.

RealGM Wiretap RealGM Wiretap. Seventy percent of African-American men comprise NFL rosters despite representing only six percent of the United States' population. While the majority of NFL players are black, the NFL fan base is 83 percent white and 64 percent male. The NFL has no African-Americans who are a majority owner of a team and no African-American CEOs or Presidents. Colin Kaepernick has received criticism from many of his fellow NFL players and fans for his protest of the treatment of people of color in the United States by not standing for the national anthem.

- Dr.Luigi Cavalli-Sforza published a map of the populations with the highest percentage of thier members with Rh-negative blood. He wrote: Rh-negative genes are frequent in Europe, infrequent in Africa and West Asia, and virtually absent in East Asia and among the aboriginal populations of America and Australia. One can estimate degrees of relatedness by subtracting the percentage of Rh-negative individuals among, say, the English (16%) from that of the Basques (25%) to find a difference of nine percentage points. The highest percentage of people with rh- blood is found in the Atlas mountains of Morocco(40%).
