Chromosomes 1 through 22 and the X chromosome are shown. In the application you can select the number of grandparents who must be from the same country and the size of the match in centiMorgans (cM). You can also mouse over a match and see where their grandparents are from, the length of the match, and, if a public match, the name of the person. Other data can be downloaded in a spreadsheet format for further examination.
The default view is of all 4 grandparents from the same country and a match of at least 7 cM in size and no Colonials.
The first picture below shows the results of looking at my matches with the grandparents matching or non-matching and the size set to the smallest length of 5cM or larger with no colonial matches. You can see that some chromosomes have greater coverage than others. Chromosomes 14, 21, and 22 have no matches. The large gold match on chromosome 1 is with someone with all four grandparents born in Norway.
The second picture has the same parameters but it includes Anglo-American Colonial countries.
