Why are the results not accurate for some of the traits?
Despite the outcomes being backed up by scientific research, there are certain limitations when it comes to ancestry testing. Such tests only serve as a comprehensive risk analysis of health-related traits and discuss the likelihood of you developing the condition. Moreover, a trait is influenced equally by other factors like environment and lifestyle as much as it is by genetics.
Lastly, the DNA raw data files from ancestry tests contain only 0.03% of your whole genome. Hence, these files may not have all the markers that are present in our database.
