Abstract
Examination of the DNA of individuals with sickle cell anaemia who reside in various geographical areas in Africa has led to the conclusion that the gene for this genetic disease arose separately in three different locations. Similar studies of sickle cell anaemia patients in the United States provide considerable information about the frequency in the United States of these three genetic variations. On the basis of such data, it is possible to estimate the percentage of slave imports from a given African locale into the United States. When this is done, there is general concordance with previous conclusions from such sources as language studies, shipping data, etc.Keywords
