Nearly two decades ago, Richard Dawkins proposed the conceptthat genes possess an inherent property of "selfish replication."1He argued, anthropomorphically, that these basic units of hereditybehave in a manner that guarantees their self-perpetuation.However, a flawed gene would be eliminated from the speciesby selective pressure against the expression of a deleterioustrait. Thus, only the most robust genes would be transmittedto subsequent generations. In this issue of the Journal, Greengardand her colleagues2 describe a homozygous mutation in the genefor coagulation factor V that seems to have no adverse clinicaleffects. Their report suggests that . . . [Full Text of this Article]
