Dating the age of admixture via wavelet transform analysis of genome-wide data

Genome Biol. 2011;12(2):R19. doi: 10.1186/gb-2011-12-2-r19. Epub 2011 Feb 25.


We describe a PCA-based genome scan approach to analyze genome-wide admixture structure, and introduce wavelet transform analysis as a method for estimating the time of admixture. We test the wavelet transform method with simulations and apply it to genome-wide SNP data from eight admixed human populations. The wavelet transform method offers better resolution than existing methods for dating admixture, and can be applied to either SNP or sequence data from humans or other species.
