August 21, 2009: We have updated the database and added 30 new or updated population samples with 4,405 haplotypes. Most of these new haplotypes have been typed in the 17 locus (YFiler) format. The YHRD has now 79,147 haplotypes, 21,800 of these with the maximal extension.
The new population sets stem from 11 countries (Brazil, China, Colombia, Ecuador, India, Japan, Slovakia, South Korea, Spain, Taiwan and Ukraine). Y chromosomes from 96 countries are now represented in the YHRD.
