In Haiti in the eighteenth century there existed a classification of physical types based on the notion that each individual was divisible into no less than 128 separate parts (rather like genes):

Thus a blanc (white) had 128 parts white, a nègre (Negro) 128 parts black, and the offspring a mulâtre (mulatto) 64 parts white and 64 parts black. The full list of classifications includes:

• Nègre (0 parts white)
• Sacatra (8 to 23 parts white)
• Griffe (24 to 39 parts white)
• Marabou (40 to 48)
• Mulâtre (49 to 70)
• Quateron (71 to 100)
• Metif (101 to 112)
• Marmelouque (113 to 120)
• Quateronné (121 to 124) 
• Sang-mêlé (125 to 127)
• Blanc (128 parts white)
