The above study has one number standing out:
Gene cde frequency East Sinai,, Egypt: 0.455
According to Hardy-Weinberg, that makes 20.7025% Rh- individuals.
This somewhat supports Kara Rogers’ claim that the Bedouins of the Sinai Peninsula in Egypt have around 18 to 30 percent rh negatives amongst them.
This is a beautifully conducted study. I like it because, unlike so many that are focused on transfusion or Hemolytic Disease of the New Born (HDNB) it asserts that there is an anthropological and historical dimension to the distribution of Rh Negatives. From what I am seeing in my YDNA forum, there may be statistical techniques to achieve more focus by using estimates of the age of mutations. I have never seen that done for Rh Negative mutations, but think that it can and should be done. A the personal level, I am a CDE Rh Neg, which is a minority mutation within Rh Negs. Establishing an estimated date for the creation of CDE could then improve the analysis of the present day geographic distributions of the multiple Rh Neg mutations and their origins.
