Is it meaningful when two or more of my matches have a DNA segment or segments in the same location?
Yes. You may all share a DNA segment inherited from the same ancestor. However, you each inherited half of your DNA from each parent. Sharing with any two matches may be through a different parent. [...]
If I have two matches with overlapping DNA segments, how will I know if they have those segments in common?
To tell if two or more of your matches have DNA segments in common, ask each to check for the other on their match list. If they are on each other's match lists, they can [...]
The centiMorgan (cM) values for DNA segments are measurements of how likely the segment is to recombine as it passes from parent to child. Segments with higher cM values have a greater probability of recombining [...]
The Family Tree DNA bioinformatics team works with centiMorgan (cM) data from the International HapMap project. Current knowledge of centiMorgan values across the human genome comes from the International HapMap project testing. The project tested [...]
Yes. Limitations in the number of global populations used and the number of samples tested in the International HapMap recombination rate studies limit what we know. SNP values at 12 locations in sequence Mother G [...]
