  • Estimates of T are based on a generation time of 20 years. Recall that N is the effective number of chromosomes in the population. The values of average NPV for the first data set are with the adjustments for X-linked loci as described in Di Rienzo et al. (1998). The values without the adjustments used to estimate T in the rapid expansion scenario are 1.272, 0.943, 0.586, and 1.048 for Luo, Sardinia, Kaingang, and pooled samples, respectively. kya, thousand years ago.
