What is BigY?
BigY is a Y-DNA test offered by Family Tree DNA. For a limited time only (August 2017), Family Tree DNA is offering BigY to existing customers for $395 (down from $575).
Typically, most Y-DNA tests taken by genetic genealogists are either STR or SNP tests. In contrast, BigY is a Y-DNA sequencing test available to male test-takers. The test sequences approximately 12 million base pairs of the Y chromosome, and identifies SNP results within those 12 million base pairs.
The Big Y product uses next-generation sequencing to reveal genetic variations across the Y chromosome:
- Targeted Non-recombining Y-DNA sequencing.
- Illumina HiSeq 200.
- 55X to 80X average coverage.
- Around 11.5 to 12.5 million base-pairs of reliably mapped positions of non-recombining Y chromosome.
- Analyzed using Arpeggi genome analysis technology for improved variant calls.
All samples are processed in-house using our custom laboratory methods and informatics. Your sample never leaves our company and is never shared with outside vendors..
