In recent years, several authors have proposed different measures of genetic distance between populations (CAVALLI-SFORZA and EDWARDS 1967, MLAKRISHNAN and SANGHVI 1969, HEDRICK 1971, and others). In many of them, however, it is not clear what biological unit they are going to measure. From the standpoint of genetics, the most appropriate measure of genetic distance would be the number of nucleotide or codon differences per unit length of DNA.
