YFull Helper 作者: Dragan Obrenović

The extension is a toolkit for genetic genealogists that enhances the YFull.com functionality by providing filtering of samples, additional information about samples on the YFull tree, as well as statistical and visualization tools that facilitate analysis of male and female lines, their geographic distributions and regional diversities. The extension allows users to see:

1) Known samples information (e.g. ancestral information) directly in the YFull tree
2) Haplogroup annotations (e.g. clans, tribes)
3) All tree subclades without samples
4) Recently added samples (new samples) only
5) Ancient DNA samples only
6) Haplogroup frequency per country
7) Haplogroup diversity per country
