Methylenetetrahydrofolate reductase is an approximately 19,301 base pair gene with 11 exons and located on chromosome lp36.3 (2). Multiple polymorphic sites have been described, with the C677T and A1298G most often studied. As expected, allele frequency data varies by ethnicity The MTHFR C677T variant allele is present in 34% of Caucasians, 20% of Italians and Hispanics, 14% of African-Americans, and <1 % of Africans (3,4). The MTHFR A1298G allele is present in n%-36% of Western Europeans (4). 

The factor V (Leiden) mutation is very common in individuals of western European origin. The prevalence is approximately 5% in the Western Hemisphere in Caucasians the mutation is almost completely absent from Africans and almost entirely absent from Asians.

Yet as with Irish immigrants, who came ashore already carrying the cultural and political baggage of Saxon oppression, the Jews version of becoming Caucasian cannot be understood apart from their particular history of special sorrows in the ghettos of Eastern Europe, apart from the deep history of anti-Semitism in Western culture, apart from anti-Semitic stereotypes that date back well before the European arrival on North American shores, or apart, finally and most obviously, from the historic cataclysm of the Holocaust. 

Sawyer went on to cite Blumenbach (indirectly, via Webster s Dictionary) and his five-tiered scheme of races Caucasian ( or white race, in Sawyer s words, comprising the greater part of European nations and those of western Asia ), Mongolian, Ethiopian, American, and Malay. He discussed the competing scientific schemes offered by Linnaeus, Buffon, and Cuvier to demonstrate the disagreement within the scientific community, but pointed out that no one includes the white, or...
