ySeq.net (formerly the DNA Fingerprint project also) from Thomas and Astrid Krahn. They were pioneers of yDNA testing and located in Germany before being acquired by FamilyTreeDNA in 2006 and moving to Houston. At FTDNA they extended and pioneered many new yDNA testing products. Upon leaving in 2013, they continued their efforts with this new organization they founded back in Germany. They are offering yDNA STR and SNP testing and of recently WGS testing as well. Their products tend to be the lead in the industry in terms of accuracy and coverage as they work to fine tune the chemistry lab preparation and bioinformatics pipeline to push the technology edge. Thomas maintains the yBrowse database of yDNA SNPs as well. Something he started while at FTDNA. Beside individual yDNA SNP testing, they are best known for their processing of WGS test results to gain the maximum extraction in haplogroup work. Recently, they have been funding Hunter Provyn to develop more useful tools to expand their offerings and the tie-up with partner yFull.
Upon acquiring an MGI DNB 400 internally, they started to offer a personal WGS product. Initially the WGS400 which was a single-end, 400 base-pair read length using the DNB 400 machine. Eventually they dropped back to a suite of offerings at 45, 90 and 150 megabases termed WGS, WGS+ and WGS++. When volume allows for it, they fulfill these using an MGI DNB T7 in Riga, Latvia. They are required to have a complete flowplate worth which is about 100 samples before they can make a run there. They also have been experimenting with the ONT long-read sequencer off and on; with limited availability to the end user.
