It was a standard version of the Illumina OmniExpress chip Genotyping BeadChip.
Microarray chips test a small percentage of SNPs on the human genome. Each letter the DNA code for the human genome (A, C, T, or G) is called a base pair. This one tested about 701,400 SNPs.[/fusion_text][fusion_title size=”2″ content_align=”left” style_type=”single solid” sep_color=”” margin_top=”” margin_bottom=”” class=”” id=””]SNPs per Million Base Pairs – Heatmap[/fusion_title][fusion_text]The V1 chip tested 701,400 base pairs across the human genome. This heatmap shows how those SNPs are distributed across the 22 autosomal chromosomes and the X-chromosome. The ranges are for counts of tested SNPs in blocks of 1 million base pairs.[/fusion_text][fusion_imageframe lightbox=”yes” gallery_id=”” lightbox_image=”/wp-content/uploads/2016/09/Ancestry-V1-Chip-Tested-SNPs-per-Million-bp.png” style_type=”dropshadow” hover_type=”none” bordercolor=”#e5e5e5″ bordersize=”1px” borderradius=”0″ stylecolor=”” align=”center” link=”” linktarget=”_self” animation_type=”0″ animation_direction=”down” animation_speed=”0.1″ animation_offset=”” hide_on_mobile=”no” class=”” id=””]
