'Jessica Mozersky has written a valuable monograph that crosses the immense boundary between history, social science and culture on the one hand and molecular methods, genetic mutation testing and predictive testing on the other....it details vast amounts of information about the history of Ashkenazi Jews, their culture over centuries and the medical, societal and racial discrimination they have endured.''I learnt much that I would have found useful in my clinical and family contacts during the last four decades.' 'Mozersky's approach throughout is valuable and most educational. She starts by telling us what she intends to do, then what she has done with the results and apt discussion, and finally she summarises and draws wise conclusions. She obviously has covered in much depth the social science, historical and molecular genetic literature.'-Professor Sandy Raeburn, in Bionews, posted 28 Jan 2013
