Walk Through the Y
Walk Through the Y is a collaborative programme run by the commercial genetic genealogy testing company Family Tree DNA and headed up by Thomas Krahn. The objective is to identify new single-nucleotide polymorphisms on the Y chromosome. Several members of specific haplogroups are required to sign up for the project. Their results are usually co-ordinated in a dedicated WTY project (see list below). The participants each have a large region of their Y chromosomes sequenced (around 200,000 base pairs), and the results are then compared. Participation in the Walk Through the Y project costs $750. Participants are either self-funded or the cost is subsidised by donations to the various haplogroup projects. Participation in the WTY Project is by application only. Prospective participants should in the first instance consult the group administrator of their haplogroup project.
