I believe they provide good information about European(but insufficient)and native americans ancestry report. But regarding the african percentage in the reports they are quite wrong. They assigned an extremely high percentageof african ancestry to people. Significantly higher and different from many other companies of dna.I had been tested by several dna companies. The reports are extremely different from genomelink regarding african ancestry. I don't trust genomelink. Customer service very poor.They always split the different reports in 13 ethnicities or 13 groups. I am very disappointed .
