The discovery of multiple alleles called into question what is meant by the gene. Two eminent geneticists, A. H. Sturtevant and G. W. Beadle, who had coauthored a textbook on genetics, discovered that each had used the term ‘gene’ differently. The white gene to Sturtevant was the specific white mutant, but to Beadle it represented the group of white alleles including the wild-type allele. While most geneticists today follow Beadle’s
usage, medical geneticists frequently refer to those mutations associated with genetic diseases as genes, for example, the Duchenne muscular dystrophy gene or the Huntington’s dis ease gene, without mentioning the normal alleles. Many geneticists, however, are adopting the compromise language of referring to the Duchenne muscular dystrophy gene ‘muta tion’ or the Huntington’s disease gene ‘mutation’ to distinguish between gene and allele.
