Studies on an isolated West Indies population. VI. Immunoglobulin (Gm and Km) allotypes.

: A random sample of 221 individuals taken from 2000 inhabitants of a small Caribbean island of French origin were typed for Gm and Km allotypes. Gm haplotype frequencies were found to be significantly different from France. Km(1) frequency was found to be lower than in the French population. These differences suggest a small degree of admixture with the Black population, and genetic drift.
