General

Search for a haplogroup and get a map with the frequency of individuals in a population. Only YFull haplogroups are recognized. As there is a difference between the ISOGG and YFull tree we cannot accommodate both.

Searching

Searching is done by typing the name of a haplogroup or SNP. Searches are not capital sensitive. The returned percentages on the map are calculated based on samples typed for the searched for haplogroup. The percentage shown is the number of samples that are typed as derived / total samples that are typed as derived and ancestral.

Besides normal searching you can make use of the star (*) notation to refine your search. It can be used to find the frequency of samples that are derived for the primary haplogroup and ancestral for all haplogroups after the star. For example if you searched for A1b*(xD,E), you will obtain the results for all samples that are derived for A1b and ancestral for D and E.

Interpolation

Interpolation is an option added to try and estimate frequencies in countries and regions for which no data is available. A region has to have at least three surrounding regions with a known frequency within 1.000 kilometers before we consider it eligible for estimation. A weighted estimate for the frequency is taken based on the distance between the known regions and the region that is being interpolated.
