Converting centiMorgans into percentages. In order to get an approximate percentage of shared DNA from a Family Tree DNA Family Finder test, take all of the segments above 5 cM, add them together and then divide by 68. The way the calculation works is that your total genome in cMs with the Family Finder test is 6770 cM.
However, when I had a test done for myself by Ancestry DNA, my results came back with around 1 percent African DNA. When painting my chromosomes [to visually highlight relevant areas], I found a moderate-sized segment that comes up sub-Saharan African on all data sets, about 7-8 centimorgans or so.
