The Caribbean Basin has the unique distinction of a myriad of different cultures and ethnicities melded together by historical and geographic factors to yield a mosaic of physical and genetic features. As a result of this mixture, individuals descended from this gene pool have a distinct genetic makeup. This makes it difficult to find a match for those stricken with hematological and auto-immune diseases, in need of a stem cell/bone marrow transplant. http://caribbeanmarrow.org/
