Y-Chromosome Browsing Tool Guide

The Y-Chromosome Browsing Tool is available on the Big Y Results - Named Variants and Private Variants tabs. This tool enables you to view each SNP or Position and its corresponding reads. 

To use the chromosome browsing tool: 

  1. At the top of the Big Y Results page, click on the Named Variants or Private Variants tab. 
  2. At the top of tab, on the chromosome browsing tool, click on the SNP or Position you want to view. The Y-Chromosome Browsing Tool opens in a new window displaying the location of the SNP.
    • You will be able to see the number of positive or negative calls for that specific SNP or Position
    • Pink indicates that a mutation, or derived value, was found for the SNP or Position versus the ancestral value found in the reference model.* 
    • Blue rows indicate that the read was on a forward strand of the helix and green rows indicate it was on a reverse strand of the helix.
      • The more intense the shade of blue or green the higher the confidence of the read.
