Melanesian origin of Polynesian Y-chromosomes

Abstract

In our recent Research Paper on the Melanesian origin of Polynesian Y-chromosomes, which appeared in the 19 October 2000 issue of Current Biology, we included published data on Y-chromosome haplotypes from the Cook Islands and coastal Papua New Guinea (Hurles et al., Am J Hum Genet 1998, 63:1793-1806). We have since been informed that the allelic designations for DYS19 in this paper are incorrect (Hurles et al., Am J Hum Genet, 2001, 68:298). We corrected and reanalyzed our data, with the result that three Polynesian Y-STR haplotypes from Hurles et al. (1998), all on the DYS390.3del/RPS4Y711T haplotype, are now identical to haplotypes observed in our sample of Polynesians. The number of DYS390.3del/RPS4Y711T Y-STR haplotypes is thus reduced from 39 to 36, and the demographic inferences (with associated 95% equal-tailed intervals) concerning this haplotype that were presented in Table 2 of the original paper should be as follows: initial effective population size in 1000 individuals, 0.31 (0.1; 0.97); population growth rate per generation × 10−3, 7.4 (1.0, 25.5); time of expansion in 1000 years, 4.25 (0.9; 15.6); time back to mrca in 1,000 years, 10.9 (4.7; 30.9). All references in the text to these particular demographic parameters should also be corrected. New versions of Figure 3a, Figure 4, Figure 5 are shown above. All other figures, tables, and analyses are not affected by this error, and none of our conclusions are altered.Figure 4Median-joining network of 36 Y-STR haplotypes from 75 individuals belonging to the DYS390.3del/RPS4Y711T haplotype.
