A Y-sequence is a substantial part of the Y-chromosome DNA which, according to hg19, is 59,373,566 bases long. See the Y-DNA SNP testing chart for a technical comparison of Y-sequence testing and other forms of Y-SNP testing.

Comparison table

This chart has been compiled as a subset of ChrisR/current_NextGenSeq_testing#NGS_comparison_table. FGC = Full Genomes Corporation, FTDNA = Family Tree DNA, see also Y-DNA SNP testing chart and Autosomal DNA testing comparison chart.

FGC Y-Elite

Since 2013 Full Genomes Corp. provides the raw data in BAM file format along with interpretation results. Download is possible after Account login or with Account Sharing from Amazon Simple Storage Service (S3).

• Y-Elite 1.0: BAM files contain ca. 22.7 Mbp in approx. 9 GB.

FGC WGS

Since 2014 Full Genomes Corp. provides the Raw Data in BAM file format along with interpretation results. BAM files according to read depth (data amount) are delivered online or by hard drive / USB stick.

BigY Raw Data Window

FTDNA Big Y

Since 2013 Family Tree DNA provides VCF (and BED) for download on the Big Y results page > Download Raw Data. BAM files for Big Y deliver ca. 13.9 Mbp in approx. 1 GB. The BAM file needs to be requested by filling out a Contact Us Form request and choosing the Big Y BAM Request category. After some business days (in May 2016 it takes ca. 2-3 weeks) the link should be available Big Y results page > Download Raw Data > Download BAM. Additionally a "Share BAM" function is available which creates a temporarily valid link to download the BAM file (expires after 1 hour). Upload to YFull with the "Link to a sharing file" normally works.

FTDNA Walk Through the Y

From 2007-2013 Walk Through the Y delivered 300,000 - 600,000 base pairs. The technology used was not NextGenSeq but the details are mentioned here.
