In Sewall Wright's review of Fisher's book, he pointed out the logical
fallacy in Fisher's ideas about the evolution of dominance. This was one
of the major points in the feud between Wright and Fisher (read Provine's
studies to get the details, or read Wright's review). Population
geneticists agree with Wright.
