let’s have a review of what genetics is all about, the scientist who study genetics are known as genetists. They carry out breeding experiments to fellow the inhe
Antigen occuring in the red blood cell on any human being around 85% and some other primites. It is particularly important as the cause of haemolytic diseases on new born babies and incapability in blood transfusion.
Rhesus positive throws light that proteins are found in the surface of red blood cells but if you are negative you don’t have antigens on your red blood cells.
People belong to the ABO and Rhesus blood systems.The rhesus system however presents a special problem for married couples.
People who rhesus antigens on the surface of red blood cells are said to be rehesus positive ; People who do not have it are RHESUS negative.
A dominant allele R controls the rehesus antigen production. Thus,
* A rhesus positive person may be homozygous for dominant allele (RR) or hetegengous for it (RR) and
* A rhesus negative is homogeneous for recessive allele (rr).
Rhesus positive also affects pregency if the child is rhesus positive, the child suffeers massive red blood cell destruction, often resulting in miscarriages,the unborn child can be saved by giving him or her a transfusion of rhesus negative blood while in the womb.
