Table 2 Analysis of molecular variance for the Y chromosome. Ninety-five per cent confidence intervals (CIs; in parentheses) were calculated using 1,000 bootstraps across loci. The World-B97 sampl [28] consists of 14 populations that were chosen in order to approximate the sample of Barbujan et a l.[26] The fifth column corrects for the smaller Y chromosome population size, as in Pérez-Lezaun et a l.[30] The estimate and CI for the among-region variance component for Eurasia are set to zero because Weir's unbiased estimator [23] yields slightly negative value
