Summary. 37 Out of 1008 Surinam Negroes were Gm(x +). 17 Out of 34 Gm(x+) Surinam Negroes proved to be Gm(g—). The Gm chromosomes, that determine Gm(x) in the Gm(x + g—) Negroes are not of Caucasian or Mongoloid origin, since in the Caucasian and Mongoloid populations so far studied Gm(x) was virtually always coupled with Gm(g). Consideration of the complete Gm(a), (x), (f), (g), (b 0 ), (b 1 ), (b 3 ), (b 4 ), (b 5 ), (c 3 ), (c 5 ), (s) and (t) phenotypes of the Gm(x + g—) Negroes suggested that Gm(x) was coupled with some or all of the Gm(b) determinants instead of with Gm(g).
