Chromosome Browser

What it's for: painting your shared DNA segments across the 23 chromosomes, colored by testing company — a visual map of where your matches overlap.

Reading the browser

Each chromosome is drawn as a bar; every shared segment is painted onto it, colored by source (the same colors as the chips in Matches).
The scope chip reads All matches by default, or Person #… when you've selected a match — this is one of the three screens that follows the selected match (look for the accent dot in the sidebar).
The summary shows the segment count, e.g. “12,430 segments” or “6,000 of 18,900 segments (capped)” when a very large kit is trimmed for performance.

The Chromosome Browser — shared segments painted across the chromosomes, colored by company.

False-positive regions are excluded. Segments overlapping your kit's false-positive regions (pile-ups and centromeres) are left out, so you're not misled by spurious matches.

Ancestry-only kits show nothing here. Ancestry doesn't provide segment data, so a kit imported only from Ancestry has no segments to paint. Use kits from FTDNA, 23andMe, MyHeritage, or GEDmatch for chromosome work.
