The highest frequency Y-chromosome signature (haplotype) was named the Cohen Modal Haplotype (CMH). The CMH is found within Haplogroup J on the Y-chromosome ancestral tree. Haplogroup J is commonly referred to as ‘Semitic’ or ‘Mediterranean’ because of its elevated frequency in those areas. However, Haplogroup J is found at its highest frequency (and greatest diversity
