- Panel (A) is the comparison between my mother and my maternal aunt (full-siblings), showing there are 2 FIRs, the green bars labeled FIR (1) and FIR (2). The table above the graphic gives the boundaries for the HIRs (half-identical regions), the blue bars, but not for the green FIR bars.
- Panel (B) is the comparison between my maternally-phased kit and my maternal aunt. This shows that my phased kit provides the end location of my mother's/aunt's FIR (1) at 37,435,730 (black line 1) and the end location of my mother's/aunt's FIR (2) at 186,250,473 (black line 3).
- Panel (C) is the comparison between my maternally-phased "evil twin" kit and my maternal aunt. This shows that "my evil twin" phased kit provides the start location of my mother's/aunt's FIR (2) at 156,185,705 (red line 2).

Since my blog posting last month, Obtaining FIR Boundaries on GEDmatch using the Little Tick Marks, GEDmatch has introduced a new Tier 1 tool, known as "My Evil Twin" Phasing, which makes it much easier to obtain the boundaries for FIRs (fully-identical regions) if at least one child's results are available; this is used in combination with the normal phasing tool.
