Note: Admixture time was estimated with ROLLOFF assuming the putative ancestral populations were Dai and French. Standard errors were computed using Weighted Block Jackknife by removing one chromosome each of 22 times. We assume 29 years for each generation. NULL indicates that no obvious ALD decay was observed.
