Abstract
Restriction maps of 145 human mtDNAs representing samples from five geographic regions were used to construct multilocus genotypes for 28 genetic loci of the mitochondrial genome. Alleles were defined as distinct combinations of the presence or absence of polymorphic restriction sites within each locus. The 28 loci included 13 genes encoding proteins, 10 genes specifying tRNAs, 2 genes specifying rRNAs, and 3 noncoding regions consisting of the D loop, the light strand origin of replication, and the 5' noncoding sequence. In 35 comparisons of allele frequency distributions to expected distributions predicted by neutral mutation theory (assuming an infinite alleles model), the results revealed that most genetic diversity values (71%) fell within the range predicted by the neutral model; however, excesses in the frequencies of common alleles and in the number of singleton alleles within populations were observed at specific loci. Departures from the neutral mutation model are most readily explained by the effects of the recent expansion of the human population and the action of purifying selection. Coefficients of population differentiation suggest that gene flow of mtDNA types between certain geographic regions may be limited.
