> which combinations of genes that express the features that we attribute to race If an arbitrarily large grouping of genotype combinations is necessary to categorize people, perhaps that categorization scheme is not useful? I would imagine that the number of "races" generated via the mechanism you posit would measure in the hundreds or thousands, rendering it unrelated in practice to the word "race" as it is used.
